I ALWAYS LOG OUT COMPLETELY BEFORE RESET. I LOGGED OUT SEVERAL TIMES WHICH MADE ME LOSE MY 1ST AS WELL AS 2ND POSITION.
No worries I will not play for leaderboard again. Who knows how many other players jumped in there with the same high score that were not even noticed by anyone. I cannot compete with this system.
The same guy stayed on the board all day yesterday and is still there today.
His score never went down.
