I was playing through the nightingale quest New Connections when I met with circle and went in the door the quest was to follow her but she just stood at the top of the stairs. I tried reloading a save from before, talking to her, trying to melee her to the stairs, fast traveling away and then back, and also sleeping for a few in game days and trying to come back but no matter what she wouldn't move is there any good fix on Xbox.
