does that mean i have to play the game from the begining to continue?
btw love the game
Yes, It's a really stupid bug that I genuinely don't take the blame for. It's some ren'py crap I had no way of seeing coming.
Start a new game, the bug manifests in weird ways, including making choices for you, changing your stats, and jumping around the script randomly.
Even if your save seems fine, it's not worth the risk. It's an incredibly serious and destructive bug and I wish I could undo the damage that has already been done to existing saves, but I can't.
I can say with ~90% certainty that it won't happen again for future updates.
