I'm not sure if this is the cause of repeated conversations, but I have had A TON of repeated conversations in acts 1 and 2, both with NPCs and companions in the playthrough where I used Disguise Self a lot. It seemed to me like using Disguise Self reset the conversation, even for my companions (which were standing right beside me). Also my companions should know it's me in disguise and not repeat their lines at camp
PS: If mind flayers don't have souls, why can we use Speak with Dead on them? Check mate, mindflayer haters!
