This story will make sense to you. If not, this post is me channeling my confusion more than anything. 

A friend and I were playing the map Der Eisendrache on split screen. My friend goes down and I rush to revive him, even though he had around ten thousand points and would've been okay coming back the next round. I manage to revive him at literally the very last second. The exact moment he gets back up, the laughter that plays whenever the Mystery Box moves played three times in succession. When it was done, my friend lost all of his points, and his gun was taken away, leaving with just the starting pistol.

What the actual hell? I'm equal parts incredulous, and curious as to what triggered that. I've been playing Black Ops 3 Zombies since it came out last year, and have never seen something like that before.
