[[Special:Contributions/130.211.0.79|130.211.0.79]] 21:41, 16 July 2019 (UTC) My dwarves had [[fun]] caused by a random cave-in that occurred in one of my soil farming layers. The area of collapse was a small room in the second soil layer beneath a river (in the damp soil tiles just below the river). This ended up flooding 8 rooms and at least 6 dwarves had some [[fun]] in the water. I had no designations there that would have caused this, and besides, if a dwarf had attempted to mine a damp tile, the game would have paused. I don't know if this is a feature or a bug, or if something was changed that nobody has been aware of. It does make sense for a soil floor to collapse if there is nothing underneath and a heavy river above, but as far as I am aware (and this article doesn't disagree) there are no random cave-ins, they are always as the result of a mined tile. I also was not currently chopping down trees (for maybe half a year or so). I just added it in as a warning not to dig in soil beneath rivers in case of cave-ins, whether it's a bug or not.

Thank you for your consideration.

:That was likely an unsupported tree growing in midair then collapsing, {{bugl|9479|cat=nocat}}. Leaving an intact layer between the surface and your fortress will prevent any collapses from breaking through and flooding your fortress.--[[User:Loci|Loci]] ([[User talk:Loci|talk]]) 16:45, 21 July 2019 (UTC)

-Trees can also remove soil floor layers, probably because of their root systems? It is interesting that dwarves seem incapable of removing trees without digging them up, since the action of removing a tree requires an axe and no digging implements. Noticed that my farm below the surface had a hole in the roof after chopping a tree. This among other tree issues can probably contribute to random cave ins. Have no idea why we need tree root systems, anyway? Lol [[Special:Contributions/35.191.2.5|35.191.2.5]] 13:39, 29 July 2019 (UTC)

-Do Ice Walls count as natural stone? The kind that water freezes into in winter?
-== Redundancy in section "Using cave-ins"? ==
-It seems like the purposes "Defense" and "Cavern Control" in section [[Cave-in#Using_cave-ins|Using cave-ins]] are talking about the same idea. [[User:Xjtu-blacksmith|xjtu-blacksmith 黑山雁]] ([[User talk:Xjtu-blacksmith|talk]]) 14:41, 17 April 2022 (UTC)
