== Dead Wagons on Depot Deconstruct Exploit ==

You can take every item from a caravan by deconstructing a depot while the caravan is in it. The items aren't marked as stolen if you do this. But in the units screen, any wagons that were in the depot will appear as deceased. It's because the trader's wagon is a creature. Specifically, it's the center tile of the wagon. That's why the Depot Access view only shows where the center tile of the "wagon" can get to. I'd kind of like to point this out here, or perhaps on the page specifically about wagons, to identify the difference between the trade wagons and your starting wagon, which is a building.

Also, Dwarves still won't siege you, and this particular exploit can make the game ridiculously easy if you only deconstruct on the Dwarven caravan.--Kydo 02:48, 25 September 2009 (UTC)

:That exploit is already discussed in this article.  And the distinction between embark wagons and trade wagons has (also) already been made clear on the [[wagon]] page (which the key word most users would Search for, I'd think - and where I'd think we should be having this discussion?) If you want to put a footnote in that article, so long as it isn't adding more confusion than clarification (that is, it doesn't devolve into pointless detail and supposition), more info can't be a bad thing.--[[User:Albedo|Albedo]] 15:03, 24 September 2009 (UTC)

::Well, the wagon article seems to focus almost exclusively with the starting wagon, and only mentions the trade wagons once. In fact, reading over it again, it only mentions trade ''caravans''. Nothing about the wagons therein, or the distinction. Still, I agree with you that this is more about the wagons than about that exploit, and the conversation should be over there, not here.--Kydo 02:48, 25 September 2009 (UTC)

== Culling on mandates ==

== Trading flowchart ==
{{:Trading/Flowchart}}
Given a number of questions on the forums, it may be a good idea to put together a flowchart of the steps involved in trading. I will draft something up here (at least partially so I can safely screw up my first attempt on this wiki)

Tasks are sequential top-to-bottom, but can be done in parallel left-to-right
{|cellpadding="2" border="1" width=400|
|-
| colspan=2 rowspan=2| Make or obtain goods to trade || Build Depot ({{K|b}} - {{K|D}})
|-
| Ensure Depot is accessible ({{K|D}})
Check green area reaches edge of map
|-
| colspan=3 | Wait until a caravan arrives on the map
"A--- caravan from --- has arrived."
|-
| Set goods to be traded ({{K|q}} - {{K|g}}) || Request a trader ({{K|q}} - {{K|r}}) || Wait for caravan to reach the depot
"Merchants have arrived and are unloading their goods"
|-
| Wait for goods to be hauled || Wait for the trader to finish their other tasks and go to the depot || Wait for the rest of the caravan to reach the depot and be unloaded 
|-
| colspan=3 | Begin actual trading ({{K|q}} - {{K|t}})
|}

Hmm. Is there a better way to show this? It may not help much as is... [[User:Kaypy|Kaypy]]

::'''Re: Adeptable's changes'''<br>I don't think the third branch is neccesary. For one, it makes it seem too wide, and secondary it implies that turning off the trader's labours ''all the time'' means that trading will happen faster - almost as if it will make merchants arrive more often. --[[User:Juckto|Juckto]] 23:36, 2 August 2008 (EDT)
:::I'd add retrieving empty bins to the bottom so that you don't end up with empty bins sitting at the depot.  When stockpiles are crowded you'll need them to deal with the sudden influx of goods.

::::Yeah, it's a bit tricky I guess. It's all in the colspan :p. But, ahhh, how do you retreive them? I thought dwarves would automatically fetch empty bins from the depot if they needed them, just like fetching them from any other location. --[[User:Juckto|Juckto]] 18:31, 3 December 2008 (EST)

== How many wagons? ==

I don't think I've ever seen more than 8 wagons in a given caravan. Is that the limit? Has anyone ever seen more than 8?--[[User:Maximus|Maximus]] 03:01, 9 November 2008 (EST)

:I've never seen more than two at a time before flooding my fortress. I didn't realize they could send more than two at a time. Kydo 14:20, 24 September 2009 (UTC)

== Mass selection of goods to be moved ==

Question: Is there a way to designate multiple goods in one selection to be brought to the depot? 

I'm getting really tired of indivually selecting goods to be moved to the depot when I have massive amounts of crafts, food, etc. So is anyone familiar with ways to select multiple goods at once? Maybe a "start" and "end" tags (for lack of a better name) and every good caught inbetween is designated to be moved to the depot? -- [[User:Dakira|Dakira]] 14:47 10 November 2008 (PST)

:Nope. About the best you can do is use the select (search) menu to get all the ones of the type you want, then enter-down-enter-down. You can flag about 200 a minute this way, though.--[[User:Maximus|Maximus]] 19:17, 10 November 2008 (EST)

::That's what I was doing previously. Are there any plans for a "mass selector" to be introduced? -- [[User:Dakira|Dakira]] 16:50 10 November 2008 (PST)

:::Not that I know of. Make a feature request on the [http://www.bay12games.com/forum/index.php forums].--[[User:Maximus|Maximus]] 20:05, 10 November 2008 (EST)

::::AFAIK, there is no good way to do this from the trade screen, which is why it's important to set up custom stockpiles and have plenty of bins. Man, I really wish you could make bins out of stone.

== Merchant moods ==

My fortress hadn't been doing too well, but I didn't know it was so bad it could affect merchants... and their pack animals. As the last merchant was about to leave the map, he suddenly went berserk and was cut down by his bodyguard, who then fled the scene. Shortly thereafter, I recieved a message that the donkey had been stricken by melacholy. Has anyone else had this happen?

:They usually eventually go nuts if they can't leave for some reason. Never heard of something like what you're describing.--[[User:Maximus|Maximus]] 03:24, 12 November 2008 (EST)
::Just got something close happening. They entered the map, and were chased off the map by goblins then the merchant went melancholy and a pack mule went stark raving mad. The only difference here is that one of them was actually killed before they left the map, so it could be he was unhappy over that. But still surprised that the merchants can get these kinds of moods and even weirder that the animals can... [[User:Shardok|Shardok]] 10:38, 5 November 2009 (UTC)

:::They also immediately go crazy if they see a dwarf that's gone berserk.  Or at least seem to do so.  (Had a merchant go crazy immediately upon entering a map near a failed-mood berserk dwarf who i hadn't bothered to deal with because he had run away from where i was working.)  --[[User:Squirrelloid|Squirrelloid]] 12:03, 5 November 2009 (UTC)

== No more dwarven caravan ==

So. The Dwarven caravan has not come in the past two years. I think, though I am not sure, that this corresponds with when I met the requirements for the Incoming King, though he has not yet seen fit to arrive. I believe I also capped the population sometime in there, but I think it was after the first year of no caravan. I don't recall in any way molesting previous caravans. I needs me some dolomite and steel bars, anyone know what's going on here? --[[User:Zombiejustice|Zombiejustice]] 02:10, 13 November 2008 (EST)

:So. I upper the population cap to encourage some immigration, and after a few seasons, the King showed up with his retinue and the Hammerer, who had apparently died at some point. I re-capped the population, and the caravan came next autumn. Was it the incoming king or the dead hammerer? Did the population cap interfere with the king's arrival? The mystery remains. --[[User:Zombiejustice|Zombiejustice]] 14:59, 2 December 2008 (EST)

::I'm on year 13 of my most recent fortress and the Dwarven caravan declined to show up this year, after 12 years of no problem.  I still don't meet the requirements for the Incoming King.  In a previous game I did meet those requirements, and that did not interfere with the caravan (though the liason stopped letting me place orders once the king arrived).  Anyway, I don't think my current fort has anything in common with what you've described, other than a mysteriously missing caravan after not damaging previous ones. --[[User:Sev|Sev]] 00:52, 7 January 2009 (EST)
:::It appears my problem was caused by a brief goblin siege that occurred when the caravan was supposed to be showing up. --[[User:Sev|Sev]] 16:48, 26 January 2009 (EST)

== A query from the deleted page Talk:Stealing ==

I've read many times that the traders count their total losses/profits when they leave the edge of the map, so as to make stealing of any sort impossible (to get away with, anyhow). Does this include what the guards are carrying (if they get killed or even just shoot off some bolts)? Or is the "total profit" concept true at all? --[[User:Maximus|Maximus]] 17:07, 27 November 2008 (EST)

:I'm pretty sure that the total profit concept is how it works. The value of everything the traders enter with is subtracted from the value of everything the traders leave with to calculate profit. There's probably something in there to account for the death of (a) trader(s). --[[User:Savok|Savok]] 21:42, 28 November 2008 (EST)

::is this still true?<br>i was unwittingly stealing everything off the merchants via the stocks screen. i dont have any steel yet, as i've not found any flux or iron ore. but every now and again, i noticed i had a bunch of steel/iron weapons/bolts/armo(u)r, so designated it all for melting, etc, etc.. eventually, i chose to 'dump' everything to see where they were getting it, and they were stripping the merchants of all their goods/clothes/everything metal xD  will they come and siege me anytime soon? my army's not ready yet! i do give good profit margins (20%+), but i'm sure the stuff i nick is much more valuable :/   --[[User:DJ Devil|DJ Devil]]

:::I've noticed that starving dwarves appear to be happy to steal food from merchants. I'm running 0.28.181.40d, and, being new to this, almost experienced [[fun]] due to lack of food. The dwarven caravan arrived in the nick of time, and rather to my surprise once they got close a clump of dwarves started hobbling their way over to the caravan. Once they got to it they started following it back to the depot (at full speed, not sure why), and then made off with a plump helmet each once the merchants started unpacking. Obviously food is rather less valuable than steel, but theoretically this too could tip the merchants into loss if you didn't buy much, assuming that profit/loss accounting is done this way. --[[User:Jenesis|Jenesis]] 19:01, 17 April 2009 (UTC)

::::I am suspicious that this tallying of merchants goods when they leave the map might no longer be true.  Due to an incident where the traders would not leave my trade depot despite having the ability I forbid all the items there and then they left.  I did not realize that this caused all their items to remain.  I kept forbidding the depot so that I could time their departure perfectly with my draw bridges and many years later realized that I had all this garbage laying around that I never traded for...then I read that forbidding the depot makes the traders leave their things.

::::I did this multiple times for each civs caravans and not a one laid siege to my fort.  They kept coming every year as happy as carp meeting a fishing dwarf.  (Version 40d16) --[[User:Frewfrux|Frewfrux]] 21:06, 2 December 2009 (UTC)

== Arrival dates ==

:I've kept track over about 5 years.  The Dwarf caravans seem to arrive around the 15th or 16th of Limestone and leave about the same time in Sandstone.  The Human caravans seem to arrive around the 12th to 14th of Hematite and leave in Malachite.  I don't have any data yet for the Elves.

==Wagons and magma==
A dwarven trade caravan passing over a magma channel on its way to my trade depot recently caught fire. Naturally, this caused lots of [[fun]], but I'm a bit perplexed by it. There was nothing flammable on the bridge - in fact, the magma beneath was 1/7 deep at best - but it looks like the wagons just spontaneously combusted as they passed over the stream. Can anyone confirm that it was the magma that caused this, or were the children just playing with matches again? [[User:Aosher|Aosher]] 08:07, 14 January 2009 (EST)

:Things catch on fire just by getting hot enough.  Wagons are made of wood.  Magma makes heat.  Have [[fun]].  If you need to check temperatures, look up Gibbed's "Dwarf Fortress Tweak".  Use the "Tile Edit" and you can see how hot it gets.  In Dwarven units.  I don't know the conversion.  But hot enough, wagons will [[40d:fire|autoignite]].

== Elven Caravan Wood Logs ==
I noticed there was a "verify" next to "carries more wood the less trees you cut down" under the Elven Caravans and am not sure if it is right or not.  Can anyone confirm this?  I have observed the stock of wood brought by the elves in two games as increasing significantly with time.  In one of the games wood was scarce, in the other wood was plentiful but to dangerous to cut down and in both I would consistently buy out all of the wood logs from every caravan.  So I had theorized the increase in the number of logs brought was related to demand conveyed by buying out the stock repeatedly for years.  However, not cutting down trees and buying out all the wood logs would tend to go hand in hand.  Also, to really see a significant increase in a specific item I would need to buy out all the wood stock from a caravan for close several years.  It is possible that both the demand and level of "production" of wood determine how much is brought.  If either is true for wood, then it might be true for other items that Elves bring.  Also, did I format this thing right? --[[User:Pencilinhand|PencilinHand]] 8:47, 23 January 2009 (EST)
:In my experience it's something more like - the more you have in stock, the less they bring. I was buying out all logs from them, and they brought ~120 logsevery year, and I chopped a lot of trees, but used them fast. Then I built some wooden machinery (axles, windmills), my stocks always showed about 100 logs in them after that, and elves began to bring only about 5 logs...--[[User:Dorten|Dorten]] 04:48, 23 January 2009 (EST)

::I did a series of experiments over a period of 3 years in my current fort and can confirm that Dorten is right and my previously stated theories are wrong.  A forts stockpile of wood appears to be the biggest factor in determining how much wood is brought by the elven caravans.  When I had a stockpile of 51 wood logs the elves brought no wood, when I had a stockpile of 0 wood logs they brought 43 wood logs, similar results were observed regardless of if I was cutting down trees during the year(though I did not test any clear cuts).  The other caravans may have brought more wood as well, but further testing is needed before I am confident in that statement, as it may have been caused by offerings/gifts.  --[[User:PencilinHand|PencilinHand]] 17:10, 25 January 2009 (EST)
:::I've done some of my own testing and have found that '''all''' caravans follow this behavior - the less wood you have, the more caravans will bring. The trick is that with the human and dwarven caravans, the excess can be limited or eliminated outright if you've requested them to bring enough specific goods to reach their weight limit - if you go a year without making any requests, they'll bring tons of wood logs. An interesting way of manipulating this further is to simply '''forbid''' all of the logs in your fortress before the caravan arrives - doing this, I've made the elves bring nothing but wood when they would otherwise bring their typical goods (tested with save backups as well). Incidentally, actually requesting wood logs via the liaison doesn't really help much, since a maxed out request only makes them bring '''4''' logs of each type (which is near useless with the dwarves). --[[User:Quietust|Quietust]] 05:47, 15 September 2009 (UTC)

==Trade Depot Color==
I know this doesn't have anything to do with trading, but it is interesting. Since Trade Depots are made out of 3 stones (or logs etc etc), if you combine stones of various colors, what do you get? I tried combining Orthoclase (yellow), Kimberlite (blue) and Olivine (green), and I got a green depot. Then I tried Gabbro (black) and 2 Orthoclase, and the depot was yellow. Kimberlite, Petrified Wood (red) and Olivine, the depot was green. Does anyone know how the color is selected?

::I'll have to fire up the game again when I get home, but I could have sworn that I've occasionally wound up with two-tone depots when I've used different stones.

== stealing animals ==

One of the objects I happened to cheat the game of was a nickel cage with a dog in it. on the units page, the dog was still shown to belong to the traders. Is there any way to change this? (or at least any [http://www.dwarffortresswiki.net/index.php/Fun fun] to be had from this?)

==Buggy behavior with sieges==

In my current game the dwarven caravan arrived, followed immediately by a goblin siege.  I crushed the siege but a couple caravan guards and a pack animal were killed.  A handful of merchants, guards and animals got stuck at the edge of the map, and I never got to trade, even though all the wagons made it safely into the depot. I was however able to make the usual arrangements with the liason.  Then I got the message that the caravan was leaving but they didn't actually go.  Has anyone else experienced anything like this?  Any way to fix it?  --[[User:FunkyWaltDogg|FunkyWaltDogg]] 23:43, 29 March 2009 (UTC)

:In case something like this happens to anyone else, I found that digging out the area under the stuck merchants and collapsing it fixed the problem.

== Limited Caravan Accessiblity ==

Contrary to the comments in the section on wagons, I do not believe you can force a caravan to enter the map at a specific point. Running 0.28.181.40d, I build a wall so that there is only one entrance to the map that is accessible to the depot. Humans arrived from another point of the map, and I got the message "Their wagons have bypassed your inaccessible site." I do see 'Depot accessible' on D. --[[User:Sfogarty|Sfogarty]] 05:49, 10 April 2009 (UTC)
:As for my experience, game first chooses the side of the map for traders, and then checks if wagons can reach depot. I had to chop trees yearly to keep fortress accessible before I've build a road.

I just had a Human Caravan.

None of my dwarves did anything. Not a single mug or gem or meal was moved to the depot. I had to disable my broker's labors- ALL of his labors- to get him to speak with the diplomat following him about like a lost puppy.

Now, I see a 'priority' setting function in the Manager. Would this be practical or even usable to set Depot requests high?

: No, priority controls the making of goods, etc. It's likely that you may need to poke your dwarf with a stick (draft him) or something. Make sure the depot is accessible to your dwarves, not only to the wagons. --[[User:Bombcar|Bombcar]] 05:21, 2 December 2009 (UTC)

== Attacked caravan slowed down - bug? ==

All right, I was in my third or so year. Autumn came and the dwarven caravan showed up - along with a Goblin ambush. Naturally the two fought in front of my fortress (with some strategic ranged support from my marksdwarves). Of the three wagons, one was destroyed (phat lewt!). Thing is, once the Goblins were taken out of the pricture one of the wagons moved *very* slowly - slow enough, in fact, that it didn't even get into the trading depot before I got the message that the caravan was going to leave soon. The wagon froze at the edge of the depot, two steps shy of getting into position, and then they both just sat there - I never even got the option to trade with them :-/ Has anyone else encountered a similar issue or did my game just have a bout of cranial flatulence?

: I have seen my caravan ambushed by goblins (killing the ambush) and then retreat... No trade this season. I guess this kind of behaviour should go in the main page [[User:MathFox|MathFox]] 17:43, 25 April 2009 (UTC)

::It seems that when you request a large amount of heavy (literally) goods, the wagon (which actually counts as a creature that hauls items) might become encumbered and move very slowly. It might even be unable to reach the trade depot before the merchants leave, especially if the map forces it to move along a long path between trees. I might wrong, this needs testing.

:::If the wagon is a creature can it get injured? If it were injured it might move slowly. --[[User:Bombcar|Bombcar]] 05:24, 2 December 2009 (UTC)

::::I had some dwarven traders arrive and their wagons got stuck on a mountain slope.  I tried digging them out but they were moving sooooooooo slowly that I reloaded (I had saved just after the announcement of their arrival) and hurried to dig out that portion of the mountain before they hit it.  The result, after they past that point, was that one wagon (only one) got stuck on another part of the slope and after being dug out moved at the same rate of slowness as I had seen previously.  The rest of the wagons moved at normal speed (having never been stuck) to the depot.  If it’s not a bug, then the game is simulating broken axils on wagons that get stuck (which I highly doubt, but would admittedly be very cool).

::::The dwarves that arrived first at the depot unpacked, but I had to wait about three months for the last wagon to finally make it and itself unpack before being able to trade.  (I’m really surprised the first ones didn’t leave.) Once I did trade they all left at regular speed except the one wagon which took another several months for it to leave the map.  In fact, it may have been longer because very shortly afterwards the elven caravan showed up and there are two full seasons between the dwarves and elves.

== requested items ==

Any time I request specific items... the next caravan turns up with exactly 1 of each item and nothing else.

So I get caravans turning up with a total of say 6 items.

Any suggestions?[[User:GarrieIrons|GarrieIrons]]
:Not sure. Maybe it depends on the actual availability of said items? In one game where I played in a pretty barren area and I asked my dwarven traders to bring lots of wood and they brought like 60 something of it the next season. When asking for meat, they bring plenty of it as well. What are you trying to request though?

:::I also suspect it has to do with the avialability at the mountainhome - i get huge loads of requested wood, meat and specific types of leather, but bit coal, lignite, pig iron, steel bars and charcoal always only come in small amounts like, 6, though still more than when i do not request them (zero :( ) --[[User:Höhlenschreck|Höhlenschreck]] 20:20, 19 June 2009 (UTC)
::::It is of course also limited by the total capacity of the caravan. In the first two years its easy to "push out" all the crap they normally bring with requests. Later they will bring everything, and more of, what you request, but still not necessarily "much".. --[[User:Birthright|Birthright]] 15:23, 23 August 2009 (UTC)

== Merchant turned friendly ==
Bug or feature? A macedwarf that came with the caravan lagged a bit behind when leaving and stopped 2 tiles from the border. When i checked with 'u' he had turned friendly. Now he's standing there guarding.. --[[User:Höhlenschreck|Höhlenschreck]] 20:16, 19 June 2009 (UTC)
:This happens whenever the merchants have all left and soldiers are left over. He will leave eventually. --[[User:Birthright|Birthright]] 15:19, 23 August 2009 (UTC)

== Forbidden Items? ==

I've never had green glass items refused by Elves, on my current or any other map.  My main export to everyone is green glass goblets on any map that supports cheap glass.  I don't need wood for them but then, I didn't think the trading system(or the elves, for that matter) was sophisticated enough to tell. --[[User:Corona688|Corona688]] 19:21, 30 June 2009 (UTC)

:It seems that the Elves only refuse items that ''must'' have been made from wood, not ones that ''might'' have had wood involved. --[[User:Bombcar|Bombcar]] 05:38, 2 December 2009 (UTC)

== Error ==
I just had my first time ever true crash of DF - right on arrival of human caravan i got a message smth like "fatal error: nemesis failed to load unit". What does this mean and how do i find out if this is a known bug and where do i report it if not? --[[User:Confused|Confused]] 12:27, 3 August 2009 (UTC)
:Okay, google was my friend. For some odd reason all the files accompanying world.sav were gone, that causes this error. --[[User:Confused|Confused]] 16:09, 3 August 2009 (UTC)

== Self-Deconstructing Wagon? ==

I had a human caravan enter my map, and right where they entered was a group of bonobos. I was accustomed to the caravans plowing right through animals with no consequences, but this time, the wagon exploded as it touched the bonobo. The wagon was nowhere to be seen afterward, just all the trade goods it was carrying (in addition to one kapok log, which I suspect the wagon was built from). The rest of the caravan promptly ran away. The only thing I had built there was a rock block road. Has anyone else had anything like this happen, and if so, under what circumstances? --[[User:King of the Internet|King of the Internet]] 00:35, 11 August 2009 (UTC)

:That happens when a wagon is killed, all of the goods fly out, the Bonobo probably attacked it, and the rest of the traders always run away if a caravan is destroyed.--[[User:CrazyMcfobo|CrazyMcfobo]] 01:42, 11 August 2009 (UTC)

:I had this happen to me too.  A caravan arrive just as a bunch of Orcs did.  I wasn't watching, but they must have toasted one wagon and the caravan fled off the map.  It was frustrating for two reasons. First, being on the very edge of the map, the clean up was terrible, and second, all the items dropped were marked as stolen.[[User:Kwieland|Kwieland]] 15:54, 11 August 2009 (UTC)

:So should it be noted on the page that normally-passive animals can attack the caravan, sending everyone back home? --[[User:King of the Internet|King of the Internet]] 21:22, 15 August 2009 (UTC)

:Indeed, I had a similar problem happen to me.  My game paused and zoomed towards a goblin snatcher, but I couldn't find the little guy.  A few frames later, he was standing in the middle of the former wagon as the horses ran off, leaving the trade goods behind for me to snag. --[[User:Alkyon|Alkyon]] 19:35, 28 November 2009 (UTC)

:Oddly enough, I've had this happen when there were no enemies, or any thief or attacking creatures on the map, in fact, wild animals at all being very scarce.  The way I put it is that the caravan vaporized on its way out.--[[User:Aescula|Aescula]] 07:41, 10 March 2010 (UTC)

== D hotkey removed in .40d? ==

I tried to see which paths the caravan could take using D: nothing came up, and it's not on the hotkey menu.

Edit: Nevermind, it's back. Don't know where it went. @_@

== Offering to the Elves ==

In an attempt to piss off the Elves, I offered them a piece of raw clear glass and they happily accepted it. Last I checked, they dislike clear glass because of the pearlash used in its construction. Attempting to '''trade''' them tower-cap logs, however, was successful in getting them angry, as was simply seizing their 30 bins of cloth. --[[User:Quietust|Quietust]] 00:11, 19 October 2009 (UTC)
:Just now, I attempted to offer them a tower-cap log and they were annoyed as a result. Exactly why they accepted a piece of raw clear glass last time is beyond me... --[[User:Quietust|Quietust]] 00:56, 21 October 2009 (UTC)

== Weird Bug ==

For some reason goblets won`t show up in the trade screen. I have some 200 very close to the Depot but they won´t show. I tried forbidding/claiming them to no avail, i aslo tried to make a goblet dump in the depot but that didn´t work either. Anyone else had this happen?
: Do any of your nobles like goblets? One of them may have [[Mandate#Export Bans|forbidden goblets from being exported]]. See [[Trading#Move Goods to/from Depot]] and try {{k|m}} in the item selection screen. --[[User:HebaruSan|HebaruSan]] 13:35, 11 November 2009 (UTC)

== Constructed Ramps ==

It seems that wagons cannot pass over constructed ramps. Could someone add that to the page? [[Special:Contributions/76.184.150.59|76.184.150.59]] 16:47, 21 November 2009 (UTC)
:They can definitely travel '''along''' constructed ramps. Oddly, they can even travel along constructed ramps that aren't braced by walls on the proper side. --[[User:Quietust|Quietust]] 20:01, 21 November 2009 (UTC)
::One of my fortresses has its entrance outdoors, only accessible by constructed ramps.  Wagons use them all the time.  I also tried building a ramp in the middle of the wagon path in another fortress (not that such a ramp could ever be useful) and it still shows as accessible.  Are you sure you're using ramps correctly?  (They have to be next to natural or constructed walls, not just floors on the next level.) --[[User:LaVacaMorada|LaVacaMorada]] 20:24, 21 November 2009 (UTC)


== No Dwarven Caravans? ==

I have noticed that if you don't have any elves or human civs near that you don't get any caravans from them, but does the same apply to dwarven civs? My fortress so far has had no contact with any race, including dwarven caravans, after 2 years. This is a two fold problem, because I don't get caravans or immigrants because no caravan ever reports my now crazy wealth. Is this normal or a bug? [[Special:Contributions/194.74.22.170|194.74.22.170]] 22:13, 23 November 2009 (UTC)
:You should always get a Dwarven caravan. Were there any reports about migrants being too scared? Is the Depot accessible? --[[User:Bombcar|Bombcar]] 05:46, 2 December 2009 (UTC)
::Maybe not on an island.  If your fortress exists on a totally water-locked plot, there might not be a way for them to get to you.  Curious how ''you'' got there, though, eh?--[[User:Admiral Urist|Admiral Urist]] 06:59, 3 December 2009 (UTC)

== Why not just go underground? ==
This probably isn't an original idea, but I didn't see it listed, so I figured I'd post it here.
Crowded maps, especially in the jungle areas, where trees will grow back and there's all sorts of nasty things waiting to eat an untended mason/woodcutter, why not just dig a wide road underground to the edge of the map, put some ramps up to the top level and then clear the caravan arrival space?  An underground road means less chance of wild beasties attacking the caravan, and probably takes less time since, if you're like me, you have more miners than woodcutters.  Plus it seems like miners are more attentive to their work than cutters.
Goblins might make use of it, but it's fairly easy to guard/trap, since it's only, say, five or six tiles across.  It worked for the Dorfs of Dragon Age, so why not for DF dorfs?

:It does work, and is great. On really evil or dangerous maps, I will make an underground tunnel three tiles wide all the way to the edge of the map, and post walls such that the caravan must come down my tunnel. Works great, but not often useful. --[[User:Bombcar|Bombcar]] 06:30, 10 March 2010 (UTC)

== Craft Bins Disappearing ==

Recently, an elven caravan rolled on up to my fortress and, when unloading their oodles of wood and cloth in the 'ol depot, I casually sent my trader in to conduct his business. To my surprise, I failed to spot "Crafts" in the Move Goods menu. At first I thought that my fatigue was playing tricks on me but upon closer inspection the category was simply gone. I selected 'sorting by distance', since the mound of craft bins is only a step or two away from the depot itself, but no Finished Good bins appeared. This is the first time this has happened to me. Pondering on it a bit I traced the problem to a mandate made by one of the nobles, banning export of crowns. Crowns are indeed a craft, but does that mean that ''none'' of the other crafts are exportable, to boot? Or is it simply that if a bin has a crown in it it's considered null in the Move Goods menu? Some insight appreciated. --[[User:Bronzebeard|Bronzebeard]] 12:28, 2 January 2010 (UTC)
: Your suspicion is correct - if a particular good is under an export ban, '''all''' bins containing '''any''' of that item will be excluded from your trade list. In order to actually see them and bring them to the depot, you'll need to turn off mandate culling. --[[User:Quietust|Quietust]] 17:34, 2 January 2010 (UTC)


== Need info on how much needs to be exported to get the human caravans attention ==

Yea I added that bit about the human caravan bieng triggered by exports, but honestly, I don't actually know how much. I just know and suspected, that you need some amount of exports to get their attention. So, if anybody knows the answer.....

== Wagons can fly? ==

I decided to fit my fortress with a trade depot that was suspended over a 7x7 pipe, that leads all the way to the bottom level of the map. I was pretty disappointed, then, when I found that the Wagon continued to mill about in mid air after the merchants had all fallen to their deaths =\
The merchant guards are lying in about 20 pieces in the recesses of my fortress, but now the wagon is hovering in "open space", and I've built floors around it but can't build beneath it to put a new depot there. Am I going to have to build a catapult and knock it out of the air or something? =\

== Value of Caravan Guards? ==

So each caravan calculates the total value of the items it carries when determining if and how much of a profit they make when leaving, right? Do the items carried by caravan guards factor into this? For instance, if an ambush comes along and wipes out half the guard, am I going to have to be extra generous to the merchants to keep them coming with more goods next year? --[[User:Loyal|Loyal]] 20:28, 11 January 2010 (EST)

== Faster than a speeding bullet wagon? ==
One of the wagons of my most recent dwarven caravan seems to be powered by rockets of some sort. The thing managed to zoom onto my screen, travel the hundred or so tiles of my entrance, down some ramps and arrive at the depot before the unbelievably agile woodcutter it passed could go more than a dozen tiles. It was the only wagon to do that, and the rest arrived several minutes later. Has anyone else seen something like this?
: I can second this, though it happened to one of my sister's fortresses and not mine. I believe she even got a video of Superwagon leaving...
