Astarion is stuck on the same dialogue and can't get out of it. It happened after the party at camp and I
chose him as the one to "celebrate" with. Now, no matter what I say to him in or out of camp, he always does the "You're eager aren't you...." spiel and I
can't talk to him about anything else anymore. Nor can I take him out of my party. I'm essentially stuck with him forever. I also didn't notice this until WAY after that scene and now I have to go back and redo the swamp and a bunch of other stuff.
