I found another one: Auntie Ethel didn't really fight back in her lair. It was normal in the hutt, she did quite a lot of damage there, but in the lair, she was just standing there. Tbh, I think, this isn't a new bug. I read somewhere, that Ethel bugs out, when you do too much damage too quickly and my party was really lucky: Ethel lost more than half her hitpoints in the initial round.
And the spider matriarch fight was much easier this time around. They seem to have repositioned the patrolling spiders, so that destroying the eggs became easier. I killed the matriarch with three characters, since my main was for some reason teleported to camp.
