Is anyone else/did anyone else have a glitch during the Yomi fight?

Everytime he gets down to about 70k health, Serah and Noel turn around and start running and won't do anything but that. I tried switching paradigms, inputting different commands, PS3 wasn't hot...it happened twice, and it killed me both times. WTF? Help please.

Oh, and also, I am at 98% on the Augusta Tower map, and can't find what 2% I'm missing. Advice?
