In Act 2, after talking to Isobel for the first time, Marcus (who I had not met yet) flew into the Last Light inn and initiated a battle. I killed him and talked to Isobel and the Flaming Fists about it, Mol was kidnapped and the tiefling kids asked me to rescue her, etc.
Later i talked to Jaheira- like, 5 hours later- and there was the option to talk about Marcus attacking the inn. I thought this was post-attack conversation I missed, but it was actually conversation about Marcus being upstairs, suspecting he was working for the Absolute, and Jaheira asking me to confirm this. She then went outside the inn to talk to a Harper in preparation of a battle against Marcus.
She is now stuck outside with the Harper. If I try to talk to her, she just has a line about preparing the Harpers for battle. Except Marcus is dead and has been dead for hours of gameplay. No other NPC is stuck like this. There is no way to tell her this.
