As mentioned on Twitter and the forums, we are working on fixing this right now. We have put the game into maintenance mode and postponed all league races for the next 2 hours to carry out a comprehensive fix for anyone affected.
Our sincere apologies to those involved. You will be compensated with Tokens and restored to your leagues to the greatest extent possible (with recovered designs, cash etc.).
