can i have your save file cause i play on android so i don't know how to edit a save file what's your progressI don't think you can do her quest, but you can use one save for test, use RpgMakerSaveEdit_0.65 and from variables change the week day to 1 and the days to 1, then try to do Maria's quest.
I also inform you that BoN makes a lot of changes to the new version and old saves won't work, so you have to start a new game.
