Excuse me, do you know how to properly update the game of downloaded 4.1.
I do not. I have only downloaded and played this game the past week or two and have only downloaded the most recent version off their Patreon. I think I remember something mentioned about using the debuging tool when trying to play from a older save from a previous version. I would check their Pateron for anything mentioning this topic. Sorry I couldn't be more help.
