never happened with me before, try putting in fewer cheats. adding too many makes the game go wierd. on one of my datas, i had 75% and had done 2 new game+'s but the cheat disc stopped the percentage from going up, so i had to restart. it does stuff like that. oh, and learning abilities, beware with that, cause for ages after, once you complete the dressphere it keeps 'relearning' the last ability for AAAAGES. it's annoying.
