Lost all my cars

I lost all my cars and I can not participate in championships! (all events are gray)
This happened after the game crashed!
My money and progress continued normal!

My gametag is marcelloxbox360

Thank you!

Welcome to the club! Some have found by holding the power button on your console for 10 seconds to reset it has helped, or try deleting your local game save data, and letting it re-sync. This exact thing happened to me, and sorry to say that nothing has helped. I’m sorry and I feel your pain.
