get on top of this ASAP! I've come across multiple rooms in which a player will be "Invisible" on the map and be able to knife, shoot, and use equipment without being detected. It has happened to multiple people whom I have played with. This seems to be becoming an epidemic and it's ruining the "Art of COD". FIX THIS ASAP! I don't want to sell my copy like I did for Battlefield 4... Don't become one of the 'Flops'!
