I just logged into the game and managed to load the save and the first thing I did was check the hearts, but there doesn't seem to be any new events, which I find weird because I'm pretty sure there are new events and the gallery is locked despite the save so I can't confirm if there really are new events.
I checked the missions and there doesn't seem to be anything new, but just for fun I'm going to play the game from the beginning. Which will be a little boring at first, but if I think there are new scenes, maybe my old save has interfered with the game...
