Dissconnected twise while in a BG game

This shuldn’t be possible. I get not letting players in when they’re trying to log onto the servers if they’re full but throwing people out mid-game? I think I’ve lost MMR due to this. And I had an almost full setup on turn 8, would have won or at least got 2nd place. Pls fix this, it’s infuriating and unfair.
