keep having system freeze when fighting sawtooth and Irminsul in void ark

Steps:
began fighting sawtooth or irminsul in void ark one of them does a weapon skill of some sort and then system freezes up forcing a force shutdown i have seen that mitigating the freeze from first person view has helped some so it has to be tied to a weapon skill animation or something, close to that of final fantasy xi's glitch where if a thf had aura steal merited and stole a buff from a monster anyone who saw the animation it would crash playonline, but this time around though seems restricted to just ps3 on these 2 monsters. and i doubt its tied to internet connection and just for some reason a bad code or something just for the ps3 version but seems a bit random i could sometimes go a week or two with nothing other times every single time i fought it.
