I was playing the Regicide daily mission today and right as I was about to kill Oryx he froze. Everything else was moving normally.
I started walking around him punching him to death and all of a sudden my body was flying across the room and I was dead. The the death screen popped up and it returned me to the game.
Only problem being that my screen was completely black. All the sound was still coming through and the game was still going on I just couldn't see anything. I listened to thrills kill me like 40 times.
I reset my console and all was well but I thought I should report this in case it's important.
