New bug report : So I don't really know what caused this bug, it could be either a problem with the save file itself or something else, but after 6 hours of gameplay or so, the character's image in dialogs will stop loading and the famous "Failed to load 'characterimage.whatever' retry?" will show up and just block the game alltogether.
The only way to get out of it is to close the game but this renders the save file unusable because the glitch will still be there.
I had to start a new game to be able to play normally, but I kept a copy of the save file in question, so if you ever need it to look into the glitch lemme know.
