0002326: Occasionally, a tile will become completely empty of all items, and count as blocked for building.
After trying to build a wall on top of an ice ramp (see 'Steps to Reproduce'), the tile became completely empty of everything and couldn't be built on - it essentially didn't exist.

To the right of the water-level part of the fort.
This is roughly what I did, I'm not sure exactly what caused it...

There was a square that was an up ramp. It was underwater, and it iced up. While it was iced up, I dug away the ice and removed the ramp. A rock was on that tile, and I needed to build a wall there to prevent my fort from being flooded. No-one would move it despite numerous dump orders and forbidding/unforbidding it, and repeated attempts to build a wall there. After a while, the square showed up as completely empty and when I tried to build a wall there it said 'blocked', but it still had the tile of a stone on it.

See 0001981. There may be more than one way to reproduce this, but it's definitely the same bug.
