I don't understand how it is done and after playing a 4 end game, which I won 5-1, it never appeared in history, as if it was never played. The funny thing is that I don't remember the name of the opponent!
I think it is just delayed. The server is down right now and when this happens game results are delayed. I am not sure if it would not record a result at all, but just check again tomorrow when the server is back up and it should be there.
