I restarted the game after getting the cat ending (with cheat mode) and now every single line in encrypted. I tried reinstalling the game but it didn't work. Do you know a fix to this?
You can try the regular reset shortcut, using the cheat mode to try and use the illusion disc. I haven't encountered this bug yet. You could also try and type "%appdata%" (without the "") into windows search bar on the left of your taskbar, then go into "roaming" and look for a folder with the game's name. Deleting this folder should remove all save data, this way if you download the game again it's as if it was never there.
