Hello.
This issue has been translated over since season 6 when I received league 11 prizes however was actually league 10.
Essentially what happens is when I go to the online adventure tab it depicts my series rewards of being league 20.
When I go in there it says my highest league score this season was league 10, which is correct, but likewise I’ll only receive league 20 prizes.
This was the same last season, except instead of it displaying league 20, it in turn displayed league 11 which were the only prizes I received.
In game it actually shows me as a league 10, even more strange is when I complete a session of ranked racing it will always say “Rank Down”, being stuck at league 20.
This is exactly the same even if I won pretty much every race and finished 1st overall.
