I can also confirm this happens.

I'm on PS4 but the 1st time I tried Shiva EX today, we had 3 people disconnecting 3 times at the exact same spot.
They all reported that the game crashed and that they were on PS3.

2 guys left and one guy said he managed to get a " fix " for this.
He said he went 1st person view (R3 when not targetting anything iirc) and looked to the outside of the arena, so no crazy ice crystal AoE would need to be rendered.
He didn't crash.

It's like a Petrification from t7 except you dont get stoned or die. You DC.
You will disconnect if you dont look away AND enter 1st person view.

Talk about extreme...
