Hello, one and all!
The situation is rather odd: I booted up Bloodlines a few months ago to show this little gem of a game to someone. Now, we reinstalled the game and loaded up the save, but there's one problem:

trigger areas are visible and, what's even weirder, you can get stuck on them by jumping!

Does anyone know why this is going on, and how it can be fixed? Preferably without starting a new game? :)

Thanks for your help!

Turning off auto-update in Galaxy, if you are using that, is kind of a must for this and many other games, especially if modded.
