DUOs one teammate came first, one second in the same game!

Played a game of Duos today, one of my partners cards disappeared part way through the fight on my screen (his Seafarer) we lost the round (percentage counter was 93%) but it didnt disappear on his screen and we won the round. I got the whole MRR second place screen and he continued to play. Luckily my board was done and I wouldnt have changed anything so he streamed and played his turn and won, gaining a first place and the first place MMR. I screen grabs of both my second placement and his first placement. No idea what happened or why but deffo a bug… I’d also like my first place MMR please - work my butt off in that game to get it as we were in a loosing position three turns before and at 2 health!
