We won the game, but FAF said we lost

[Cardvan]

Hey!
Me, Vimes_P and Dior just won a game on Twin Rivers with L_i_v_e, Ronfante and crypticfire. Faf says that we lost, but if you watch the replay you will see, that in the end Vimes_P destroyed them and there even was notification: Vimes_P wins. There were some connection problems in the middle and our teammate, Dior was disconected.
Can you tell us why it happened and maybe fix it?

most likely some people in your team left the game with Alt-F4 or failed to submitt score in another way
