Hi, I'm doing the last quest of TDD about Cyric. I went back to Candlekeep, did the quest in Eastheaven and now I'm back to Suldenessellar. A cutscene starts, after a while a man finds Larala in the meadow and while he says "Please..." the dialogue starts to fade, but remains grey cause the game is stuck there. Try it 3 times, but it's always the same.

I have a Big World Project installation so now and then I have to fix some little issues, but I have no idea how to fix a problem during a cutscene and what to check so I'd really approciate some help or advices.
