It looks like that object (an NPC)may be from Juniper's Twin Lamps mod. That NPC (named Nagera Salvu) should be in one of the outside Balmora cells. Maybe there's a mod conflict or installation problem.
You hit the nail right on the head. I unchecked Twin Lamps, and the problem went away. I should have stopped and thought for a minute "tl_....." = twin lamps.
Thanks again
