Anyway, this games as well as FF1 have a pretty bad bug when the app loses focus. If you are in the shops or similar dialogue boxes when the app loses focus, resuming the game will have interesting effects. Characters' names can get mixed up and spells and items can be lost or horribly glitched.
Try to avoid using the resume feature at all if you can help it.
