Okay--I've fixed the part of your save file that was making the battle not load (it was the nextBattle bit at the top.)
I noticed that neither Teresa nor Phoebe is on your roster, despite the fact that neither has their "died" variable flagged. Did they die at some point earlier in the game? Or did the game just fail to add them to your roster? Anyway, I've added them back in--I'll take a look and see why if I can figure out why they be missing like that.
