I went through Southfringe Sanctum to get the staff for Enthir. I set Selveni Nethri free from the spider's web and turned her loose. But now I have a quest to help her get out of the cave and she is stuck so close to the cave's exit that if I get too close, I get dumped out into Skyrim. It looks like I will have to backtrack to a reload of a previous save, but I'm asking the professional gamers here if there's another way to do this.
