Fighting party members and charm
Not sure if this is a bug or not but it is certainly counter-intuitive. In my current playthrough, Shar-Teel started a fight with Dorn. I wasn't expecting it, because there was no warning and everything I have read suggests this only happens if Dorn first attacks another female party member. Anyway, as soon as both Shar-Teel and Dorn left the party, I cast dire charm on Shar-Teel to try to stop her from attacking him. She failed her save and was charmed, but I still had no control over her. Basically, the dire charm had no impact whatsoever.
