Hmm, makes me wonder if there is a new AI issue where the enemy won't cast something that is actually helpful to you. IE a poison effect on an undead character...
Except, Isbeil doesn't "cast" anything during that scene; all she does is turning the wheel there.
If possible I may send you my save to see the problem.
Could you attach a save right before that part, if it's not too much trouble? Must say I'm curious about this; I'm not getting any problem in my save.
