Just had a case were the first carpenter I placed was buggy: Most of the tiles under the carpenter were "free" (so they could be walked and built on) and some supposedly free tiles near the carpenter were marked as having an object on it. Couldn't reproduce this so far. Probably best to keep an eye out for this issue reoccuring and documenting it here of it happens again so that I can find similarities.
