I can only speak for act 1 currently, as I started a new playthrough over the weekend.

So far no problems, on the contrary, the game feels better than ever and I got a lot of interactions, I never had before. The performance is great, way over 120fps on vulcan, no crashes, no corrupted save files...

Some things in act 1 are still not adressed (and probably never will) like Shadowhearts first romance scene occuring twice. All in all I'm slightly optimistic for the rest of the game.
