Working on the Unseen Visions quest on Xbox one. I entered Ancestor glade and Serana didn't follow past the entrance. I completed what I needed to do to read the elder scroll and it says to talk to Serana, she isn't there. I try to leave and the exit is blocked with a wooden gait that has a bunch of baddies behind it. I messed around in the area looking for a way to open the gait for a long time. I decided to look it up and Serana should have been with me and after talking to her the bad guys are released. I don't have any saves outside of the glade and I can't get out. Any Ideas?
