Myself and three other people, were playing coop on chapter 2, episode 3, on legendary, and halfway through, all of the covenant disappeared. I don't mean they had camo on, they literally disappeared. All we could see was their guns running around on the ground and our reticles would turn red when we pointed at them. We didn't see the normal silhouette that you would see with the camo, they literally disappeared. Is this normal or a straight **** up on 343's part?
Is this related to the wall glitch for war games on complex?
