On a few occasions I have seen dead player bodies stuck in some weird loop.
First time, the body was sliding along the ground then would disappear only to reappear a few meters away, the slide along the ground and vanish again. This seemed to be on an infinite loop.
Second time, there were about 3 or 4 bodies in Balota. They were floating down from the ceiling to the floor and then vanishing through it only to reappear from the ceiling a few seconds later and fall down again. It was like some weird cascade.
Tried to get screens but for some reason print screen won't work, apologies.
