Could be lag, I guess. But usually if I'm lagging the enemies will be teleporting around and not taking damage. Everything seemed to be going fine up until that point. 

Happened to us on friday. On our second attempt on vosik 2 of us died in the clean room.

So basically teammates were dying in the clean rooms after the shield was activated. Has anyone else noticed this? Could it just be an issue with lag? With the group I play with sometimes the connection isn't great when there are all 6 of us, but no one said they were lagging. It was really frustrating as the times it happened we only had one phase left and would have surely downed the boss.

WotM clean room glitch?
