I was playing on server MI 2575 yesterday on PS4 around 10:45 pm eastern daylight time (UTC - 4:00) and me and a friend were killed after finding a crate when another player sneaked up behind us in the locked house where we looking into the crate and seemed to shoot us both with a silent and invisible weapon. I know the invisible weapon is a problem which has happened to other players and therefore I am not sure if this player was using a cheat mod or if we were victims of a simple bug. It would be great if this matter could be looked into.
