I had only <CHARNAME> selected.
Upon reaching Isra she would change her stance from idle to the action stance for an instance and then return to the idle animation.
Her romance talks progressed normally and her banter talks also worked without problem.
Still I can't initiate dialogue with her.
It is something that I have observed on several NPCs in BG2EE (or EET). Sometimes they show the reaction described. If you move party members around a bit and try again it mostly works after a couple of attempts. I have not found any reason for this behaviour yet, but Isra is among those who show it (but not the only one.) Being persistent I could get any of those to PID talk after some attempts.
