I'm sure there is some internet magic at fault, but there a certain players who have leaped across great distances or even flashed to another location, not teleport, to get kills.

Also they can cause my character to move in reverse pulling me back to a kill even after moving good distances.
I've even been pulled out of a kill after the entire kill animation has completed and my score subtracts the once added kill.

I try to avoid those specific players but would like to know why it happens and if there's a way to counteract the craziness.
