Summary0002723: building a wall over an up stair in ice, removing it, then removing the up stair makes void, blocked tiles
DescriptionWeird bug that results in void tiles (blocked, no name tiles. Think "hidden," but can't be mined or otherwise designated).

If you look at it: Nothing, like hidden tiles. Try to build on it: blocked. While the layer above reports empty space, channeling into the tile from above does nothing to it.

Initially found and repeated on the ice/rock transition where other weird things happen. Checked in a normal ice layer on a hunch a few levels up and got the same result.

Seems to work fine in rock: you get the rock floor back.
Steps To Reproduce1) Embark on a glacier for ample ice layers. Not sure if this is required.
2) Dig up stairs into an ice layer.
3) build a wall/pillar on an up stair.
4) remove the wall/pillar, up stairs remain
5) remove up stair/ramps on the tiles occupied by the wall/pillar

Ah, hell. Probably not. All my searches included "tile" in them. "void tile" and the like, so I didn't see 0001981.

Yeah, 0001981 didn't have a very searchable title. I'll fix that now.
