I have the same bug and it also corrupts saved games. If you exit the game with the bug, and load it and try load an older save both of them ends up corrupted. It feels like a game-breaking bug considering it prevents you from progressing(EDIT) in the game. The times I've encountered is especially in the Submission area, ,pecfically in the Bat Cave leading up to the island where the siblings breaks the fighting UI. In the same area the map doesn't update properly and breaks entirely when the enemy/loot encounter pop up lags behind and you rush past them.
1: You can't see where you are going unless you zoom in and out of the map while taking step by step.
2: You can't loot enemies inventories
3: During fights enemy's HP nor your party's is updated correctly
4: You can't enter your room to sleep (This has nothing to do with "sleeping too long" since I specifically avoided doing that.)
(4)5: By pressing fast-travel you can enter your bathroom to wash yourself, but you can't leave the room anymore.
6: I've noticed that harpy bug with other enemies as well and those times they freeze up the UI entirely, making it impossible to continue without exiting the game
7: I don't know if this is true, but I feel like the more times you save the more likely you are to break the game.
8: I noticed when the first time I progressed to Lyssieth and the choices you need to make, and I regretted my choice and decided to quick load an older save. I had to go back further than I would have liked to (a mistake) and when I started up again it wasn't possible to get to that point of the choice anymore because of problems that occurred because of it.
I'm new to this game and these forums but I kind of feel like its weird and, I don't mean to be rude, a bit
naive to rush and release versions that are this unplayable. It is the author's prerogative of course, but using the players as bugtesters makes it kind of hard to enjoy playing the game. I can understand that you might not have the time to go through it all but then you should probably slow down the releases rather than the opposite - or let some devs help you with the smaller projects in some way or another so you can focus on the most important problems. For a player these game-breaking bugs is incredibly tedious considering there's not really any solutions to them other than waiting for another version, which would then likely introduce new bugs if no testing is made before release. I realized now that's why they call it "unstable"-version since no testing has been made? If so, this thread should seperate the releases in different links so people, who don't know this (like me), doesn't have to go through these tedious obsticles.
Sorry for the wall of text!
