Same issue here, and it's not a bug as far as i'm aware. When a player leaves, the game has to disconnect as you can't play with yourself. And you must play the full match, so 90 minutes + Extra time for the win to register. The opponent (or yourself) cannot leave here and cause the issue as the server already counted the win (or loss, or draw).
So it happens because the server HAS to do that, instead of awarding the forefeit victory.
Why do they say this isn’t a bug? The system that awards a walkover when one player leaves during a match is far too unstable. Why isn’t EA focusing on that?
