- While playing the game co-op it will randomly switch my character to be controlled by my co-op partner. This always happens in the middle of a fight - When we load in a game, say we are reloading after messing something up or whatever, the game will not load any weapons and armor for the person I am playing with but I see them still. -When exiting game after prior bug I am unable to launch game for a bit. The error reads 'app already in use' from steam.
