Viper Boss Arena Bug

It is possible to dodge roll out of the arena in the Viper Natuzi fight at the exact moment the soldiers on the perimeter advance inwards. This bricks the fight and I can't exit or log out to fix it.

I had a case when Viper lady jumped out of rectangle of her soldiers and me being melee I had no way to keep hitting her without getting hit by soldiers in front of her. Probably if I had some ranged attack like sunder I could get her and cheese this fight that way because she seemed to be stuck there and wasn't following her phases, just kept repeating one attack where she jumps up, spins around and draws circle in the ground with her spear.

So long story short something is a bit wrong with colliders on these soldiers and their interactions with fast moving player or Viper lady.
