i thought i noticed the other day that it wasnt registering my wins/losses (not that i have many losses =) then i thought it again today so i tested it. i raced 5 times and won all 5. i went back to the leaderboards and it only registered 2 of the races i waited a good half hour incase it took time but nothing. =(
ive only noticed with supercross i havent tried with the others.

i see theyre tinkering with the normal leaderboards at the mo, i hope this one gets fixed soon too.

its a shame such an awesome game has so many bugs n ****. no matter tho! im half way through super metroid on Zsnes, should keep me going until its all fixed.
