There are two achievements in Trials 2: Second Edition that are tied to getting top 5 and top 1 in a level's leaderboards. There are several cheaters that have ruined the leaderboards, making it impossible to get the top ranks in any of the levels.

Since there is work done towards achievements in most Ubisoft games lately, can you look into that as well? Either remove those achievements, reset the leaderboards or remove the cheaters' times.
