Splitscreen glitch

Was it only beta concerning, but Splitscreen sometimes crashed multiplayer. Never happened on private splitscreen, only on online. But it was like 2 characters were stacked, and only one weapon was shown. Later when countdown was ready, and doors opened. Other player was ok, but other players gun were stuck, and wasn´t able to use it. Only way to fix it was to quit, and make new game.
