sami's workout corruption is not working properly it shows as unlocked before you get the scene that unlocks it and when you get the scene that unlocks it it locks instead
i am not sure if it is all of them i found this while trying to use hp restoring items i think you should make sure those work right or make items meant for healing during battle as those are the only items worth using in battle
there is a problem with using items in battle where it brings up the field menu and removes you from battle then for battles with scenes either showing the before battle scene and restarting the fight or showing the after battle win scene after you close the field menu
