not sure exactly what I need to do in order to replicate this, so I'll keep it brief for the moment.

as a Dwarf Berserker, I've been able to re-enter Reknor once I've completed the quest, but one time I went back in and there was another copy of my character sprite sitting on top of the exit back to the Iron Throne. it wasn't my squadmate - it was like a mirror image of my character. I didn't examine it fully, but it blocked access to the stairs to exit.
