We finally found the bug that causes the blue slope time trials leaderboards to be flooded by seemingly random best times - and fixed it with today's patch.
With that done we were able to clean the leaderboards the following way:
We rolled back Time Trials scores to a backup from last July 2nd to make sure everything's clean and fair again. This means new blue slope time trials records over the last week will be lost, black slope times will be restored next week.
Trick mode and FreeRide scores are not affected.
Critical: Zen mode does not submit leaderboard entries for time trials anymore ːsteamfacepalmː
Thanks a lot for all your patience, we hope you enjoy trick and freeride mode while we are already working on our next exciting update.
your Megagons!
