Gamebreaking bug in abandoned library "under room" [spoilers]

[Fallowsthorn]

I have the magic flute, the glasses frame, one of two lenses, two of three "snake keys," one of two Medusa keys, the "golden necklace crystals," and I'd just opened the wall with the "circle inset" ring puzzle. It wouldn't let me put the gems in the statue, and when I asked for a hint it pointed me to the result glass on the potion table. When I clicked it it sent me back to the previous (currently blocked) areas, and when I tried to manually go forward I ran into the "visit all nodes exactly once" horse minigame, which is already complete and therefore impassable, and now every single area on the map is locked off. Clicking hint makes the noise and reacts visually (the bottle drains as though it's telling me to go to a different screen) but doesn't point to anything. Quitting to the main menu and reentering the game puts me back at the horse nodes minigame, but now it's blank with the horse at the wrong end and unmovable. I am not impressed.

Same here. How do you F up a basic HOG so badly that it has a game breaking, save destroying bug like this? This wasn't the first game stopping bug I had with this game either. Previously a minigame broke and became unwinnable, but at least in that case the game reset to an earlier point when I exited and restarted.

I have encountered this same bug. Suddenly I was at a location already been and cannot get back to the end area.

I am also stuck in the same position, I have contacted Customer Support but do not expect a favourable response anytime soon. After all, they have got my money now!
