I was in Silver 1 yesterday and when I logged into a ranked match, everyone was Rook 4. This happened 2 times yesterday. Today, I got to Silver 4 and the same thing happened. My RP got fully reset to 0. I was in a team with randoms yesterday. Today, I was in a party with friends but only my RP got reset and not theirs.

I finished in P4 last season and after the reset, everything was fine on Tuesday. The first time I experienced the issue was yesterday.
