[poe 2] Zarokh one shot bug

I've just had a run end like this, did first time-stopping phase no problem, after he came back in arena, took him down near quarter life left and then says the line to start the time-stopping phase but my character instantly froze and then my run ended as the little hourglasses appeared after he boops me, seems that taking his hp past phase hp thresholds too quick is casuing this, needs looking into please GGG, too scared to do another 80level run only to die at the end cause mechanics being buggy
