Currently on Act 3 Chapter 4 facing the Kraken. Finally the rocket was burning the Kraken so me and my co-op partner ran down the tunnel. He dies at the end but we also got a checkpoint.
It loads up, white with nothing else. Only to be described as taken to heaven kind of white. We decide to load the previous checkpoint. And now the Kraken wont breach the door and allow us to fight it.
86% through the game on insane and it now appears to have broken…help please!! 
, you should try an other time, I’ve got nothing help to help you instead good luck
