Re-balancing update
They just updated the game with some re-balancing.
The updated it online and not as an update in the appstore, so open the app and it will automatic change to the newer re-balanced version.
I was in rank 19 and campaign 9/11 and was stuck, as in i couldt upgrade my karts anymore and the levels required a too high CC, now they made changes and made it easier.
Not sure wat else they changed, if anyone noticed any more changes, please post it below.
Also, not sure if they changed the bugs with the strike out sub zero karts.
Thx
