man I was afraid I hadn't saved it, but I did!
It's kinda interesting to try and play this for the first time without using the cancel/select bug on purpose xD (sometimes I'm just really indecisive about what actions to take xD) I realize now why spells are cast so late. Besides taking longer to prepare, this way you can avoid wasting all your mp if you cast a spell that doesn't get played until after the battle ends xD
