2v2 RM bug ?

Hello everyone,

Yesterday I played some 2v2 RM. Long story short, my teammate get destroyed really early and resigned. Still I was doing great so I kept playing, up until the point where I could hold both of them and even destroy their base and economy.

At some point, one of them resigned and then the game kind of froze. I could go all over the map and select any unit or building, exactly the same way after a game normally end. The thing is that the 2nd enemy didn't seem to have resigned. So I waited 5-10 min like that and then quit just to see that it was counted as a lose.

Is it some kind of known bug ? Did it happen to any of you ?

Thank you all in advance
