yep its a bug,i often watch top 50 in r10 since i played there (a bit nostalgic) and he had 40 k mp and 40 k net at some point..later he grew and had around 60 k mp i think was within top 5 mp since there is only few marshals,and now i sort it by mp and hes not in there
ill report it to mods section i hope it will soon be fixed
