FFVI: Divergent Paths

I've had that happen too, but never 3 times in a row. I THINK it has to do with the characters you bring into the final battle. I'm sorry that you're getting this. Try beating the battle without Kappa or Umaro in your party. If that doesn't work, send me a savestate from right after you land the final blow, when Kefka is fading, but before you exit out of the battle screen. I can use that to try to figure out what's going on.
