Well second play-through now, and certain variables are getting reset on game-load. Last play-through it was the flute quest being reset, to the locker retrieval part, even though the full flute event had been completed, which breaks the progression of that event. This time it's the mother's quest has reset to the part where you take her to buy a necklace, and then can partially progress, until you reach a block; currently stuck on checking the car, because the car has already been fixed. This bug only happened during loading the save file, as the event wasn't bugged during my last session, but happens loading any of the 6 save files I have.
