Yeah I tried to import my old saves into 4.3.1, and it broke Rina :( though that was to be expected, do you think you could add codes we can use to skip having to redo everything?
Edit: Rina my fav character, kinda the only reason I open the game.
Most of the changes are from the latest version. But since I don't plan to revamp anything else for the next version, I can try to see if I can put an option to jump to the new content in the next update.
