Each update its best to play from a fresh save, that'll solve that error screen that you're getting in the Gloryhole section. The Witch content you can find by choosing dialogue options with the Witch's colour indicator as often as possible
Okay, I'll try it with a new savegame. And yeah, I remember the thing with the indicators, you told me a while ago when I asked for some kind of guide^^
There should be an update out in a few days that will hopefully fix any other issues you encounter, I know there's a background display issue for the new scenes that's already fixed in next version
