Another bug that's been present in the last couple of patches is Astarion's dialogue about Cazador. Even if he's talked about Cazador multiple times you still have to ask him who he is after you meet the monster hunter.

It used to be that, when you talk to Astarion after the first time Cazador is mentioned, he explains who he is. Now you can't get that particular dialogue until after you meet the hunter.

It's all very confusing/immersion breaking. I'm sure it will be fixed at some point but I thought I'd mention it in case the devs are unaware.
