Tonight I was booted from one game on Narrows in a very unusual way. It was a weird game because apparently all players on both teams except me were deranking.
One of my teammates just bumped into me and then jumped off the map. Somehow it counted as if I have betrayed him even though I didn't shoot at him. I didn't even move. After that he approached me, hit me, bumbed into me a few more times, and jumped off the map. Again I ended up betraying him without doing anything at all, not even moving. After he did that for the third time he booted me from the game.
Surprisingly I can't find any record of that game. I have a gap in my matchmaking history (the game was on 12/28 around 1:20-1:30 AM). I have reported that player as cheater.
I can't mention that players' gametag here due to rules, but if this happens to you please make sure to report the player to Bungie. I hope he'll get what he deserves.
