There is a quest called 'Search the cellar' in the blighted city where you are tasked to find a certain gem and a book. When I read this book it initiates a cinematic and the game freezes after a certain point in the cinematic, regardless of the character I use to initially read the book.
From what I can find PC users aren't having this issue, and I was wondering if anyone else on stadia has played though this quest successfully.
I haven't played that far yet, but I'll keep an eye on that quest.
But even though it seems for you to only appear on Stadia and not on PC, I would definetely recommend to leave that also as feedback to Larian so that they can work on a fix for it. Either on the website or by writing to support@larian.com.
