no, I haven't odified anything, however this morning the altivirus warned me that the program (the game) kind of could change an internal file, however already since yesterday when I finished the murder case it wouldn't let me scroll back
Well, I've never seen this happen before. All the config and rollback settings were looking okay, but it still had disabled it. I'm baffled.
I can ask the RenPy developer about it, but I won't hold my breath about getting a reply :D
