Problem
Kicking the staircase in the upper levels of the bug temple and minotaur maze can make the "dungeon" collapse and crush you, despite the fact this makes very little sense.

How to reproduce it
Go to the upper level of the bug temple or the ancient street above the minotaur maze (dealing with any hostiles in the process), then 'k'ick the down staircase many times. Eventually they will collapse and kill you - this is despite the fact that BUGWL is a completely open-air location with nothing to fall on you, and the stairs in AR are under a roofed area but do not physically support the room (I would think!).

Notes
Perhaps the BUGWL staircase could collapse the level below if kicked too much, leaving a ton of rocks in its place and preventing entry forever?
