I have found two more issues in act 3 in my current run:
1. After killing Ansur, we are supposed to talk to Ravengard, even though if we still didn't free him (according to the journal)
2. After freeing Ravengard, Wyll is telling us to hurry up and free him (in camp)
This is really confusing if you're not metagaming.
Also, here's a bug:
Blew up the steel factory with Minsc as a beast master in my party and after getting out, the wolf (his companion) is still stuck inside.
Besides that:
I hate that the whole fireworks situation is disintegrated in the game. You blow everything up as the only solution - ok, thats not a 10/10 game solution, but ok, I can live with that, fine, but having to deal with guards afterwards is another thing. I mean, it's doable and I didn't aggro the whole city this time, but it's overall a very annoying quest, the most annoying one.
My wish is that this quest gets turned into something more meaningful, where there is a different solution, like with Kagha in act 1, for example. Not "just kill everybody blindly".
