Not sure what happened, I did this zone on my main character a few days ago but after this mornings maintenance I cannot complete it. I have tried it multiple times and once I go into the vault the lag makes the place completely unplayable. Either it sticks me into an endless loading screen or it does load and you cannot do anything, if you get into a fight your character just stands there and dies because it will not respond to anything you press on the controller other than the joysticks.
