I'm not sure if this has been mentioned in any of the numerous and long bug threads, so I thought I would throw this one into the mix. If you kill a monster that is directly on the tile for a downward staircase it crashes the game. I'm not positive if it only happens when a loot drop also occurs or not (mainly because the crash has already happened). What happens goes like this: - Kill a monster on the staircase - Your character get stuck in the walking animation forever - Clicking on the game window will eventually bring up a 'application has stopped responding" message.
