The mini quest which has you saving people from a burning building that was attacked by drows and gobelins is bugged: failing to find a lever to save the man under the rubble seems to cause him to faint, but as soon as you walk down the stairs and break the door open, he both comes back to his senses AND magically teleport away from the rubble. A shame he then is stuck frantically ordering you to find an exit. Which you do. Multiple times. Only to watch him never follow you.
