They end up in the ceiling when fighting near the exit.

Screenshots and locs please, these help staff understand what particularly went wrong. Fraps would be great as well.

Haynar listed a bunch of variables in his updates, not sure which are all applying here and when (did it go in ceiling right away? only in flee mode? after a nuke? did a 'change form' occur for the mob?).
