Now that this crazy heat as subsided, I continued the campaign and went into Amadia's sanctuary. I was trying to sort out my inventory to trade with Exter, and had to listen to Duggan and Leya repeating the same things over and over and over again, in a loop... I finally gave up and went away.
It's really sad such basic QoL issues are still there to pester players and break the otherwise fun experience, so long after the first D:OS which had the same problem, after all the revisions, and all this time. Looking for a mod, I found this 5-year-old thread
, which shows how much it was already annoying players (except for one guy trying to convince everyone else that it shouldn't change because it was fine for him, typical).
Let's just hope they don't do that yet again for Baldur's Gate 3.
