Here's another bug:
In the Myconid Colony my pc started a conversation with the woman whose husband is missing. While my pc was talking with her, Astarion, who was following, triggered automatic dialogue with Glut. I tried to end the conversation with the woman with the missing husband through the leave dialogue option, but it didn't end the conversation, and the PC remained stuck as if in dialogue.
Not sure if it is a bug or intended, but I wish the conversations that trigger automatically would do so only for the pc and not companions (unless related to a companion quest).
