Summary

0004147: Building floors/walls next to grates may cause cave-ins when constructed in a certain order

Description

Dwarves will construct floors/walls in whatever order they feel like, so when you have a grate, some tiles might get constructed when they're not connected to anything at that point, and cave-in.

The specific situation that caused the cave-in was:

.....
.#+#.
.#+#.
.###.
.....

The grates were built beforehand, and the floors were designated to be built afterwards. Dwarves chose to construct the middle one first, causing a cave-in.

Steps To Reproduce

1. Channel out a 3x3 section.
2. Install grates in a U-shape, leaving two tiles empty.
3. Build two floors in the empty space.
4. If dwarves build the middle one first, it will cave-in.
