It’s annoying to find out the hard way not sure it’s wore or better than plus mode but it’s good to know, don’t delete a beaten Normal mode and go into hard, just use chapter select, not sure you can’t just change to hard at the boss for a album unlock come to think of it, sort of like a Bravely Default boss fight cheats (only did it for Golem to save time) where you can beat them on easy and play on any other mode the rest of the time (might effect last boss in BD). So, just so you know.
