Thanks for the feedback! After modifying my animations and limit setting I thought I fixed the problem. However, I have encountered it once again and it also happens when I have Hades materia paired with added effect on my attack. That and All Creation inflict multiple status changes and the game "freezes" up again in both instances. Seems like the status changes (sleep, frog, poison, confuse, maybe stone?) are the cause of my problems. I'll keep avoiding those types of attacks for now but I'm curious if anyone else has had these problems too.
