Ok so although it may seem weird, I have video proof of this too. My team lost a ranked game, and instead of losing as much as you normally do, or getting the normal message, we all got the message that we were copper 5 and unranked. It seemed weird so we checked our rank and we dropped 130 mmr. Again, I have video proof of this bug. It affected everyone of us. My Ubisoft connect username is W0ahThere. My Xbox gamertag is N0tfun.
