I don't know entirely to whom these two rooms belong, but there's a nasty interaction I've stumbled across. First, there's Dredmor's school, the one involved in my instance of the bug is Dredmor's class on transmuting dead adventurers into metalworks. The other room involved is a DL9 specific (I believe) sigil puzzle (Solve Ye Puzzle, Get Ye Reward), featuring a 2column 3 row puzzle, and lava around the edges of the room. The bug: The sections of the dredmor classroom wall that are adjacent to this puzzle room are cut in half, literally the top half is missing, and the "walltop" texture starts at the cut point, thereby "lowering" the wall. This I mostly consider a bug due to it cutting a fine portrait of Dredmor in half. To be clear, the rooms are arranged as so: ----------DL9 Puzzle Room Dremor's C[door]lassroom
