I won a game and won about 35 Elos. Then I sit in again. On the top left the correct number of Elos was shown, but not in the game under my Name. I sit out and in again, and the wrong number was still there. Then the game started and I lost about 6 Elos. The new Elo number was calculated from the wrong Elo's. So I have nothing from the 35 Elo's I won. What went wrong?
