Im playing on Xbox. 3 times I fight against the same guy and 3 times the game crashed and back directly to xbox main menu. He is the only one I have fight that have abhorat with full 3 traits, thats why I think the prob come from the 3rd trait. For info, I was also using abhorat (2 traits) on 1st position for killing him and his abhorat was on 3rd position and the crash happen when I make a skull combo that will kill him. I never ever had another game crash facing any other players.
