Summary0013549: Mushroom Cap Trees Deleted from Existence when Ramps Deconstructed
DescriptionYesterday I discovered that mushroom cap trees (like tower caps) have invisible ramps. I was try to perform a cave-in and deconstructed one of these invisible ramps. The whole tree disappeared, no logs, no nothing. I've tried deconstructing another tower cap tree to confirm what happened and I saw the entire tree be deleted from existence.
Steps To ReproduceFind a mushroom cap three (i.e. no branches) with a CAP that is at least two z-levels high
Buildup to reach the top of the cap if needed
Use the building deconstruction option in the mining menu on the 2nd z-level along the edges of the cap that have a cap tile below it
Sit back and watch I guess...
Additional InformationNot a game breaking bug but.... a very ODD result.
