Same thing happened to me twice in the past 24 hrs...one to Yojo, and then other just now to Patrice. Both times I had won, but when the game restarted it showed me as having lost both of the matches.
The good thing is that both Yojo and Patrice revenged me, and I was able to revenge them back, victorious again for both fights, and this time THANKFULLY my victories were registers. HA!
