I recently lost a lot of upgrades(all drive trains were set to 0) in a cloud restore and didn't notice at first. After saving and restoring to a backup device the game noticed I had less upgrades on all of my cars and deleted all my time trial results (WTTT and career).

Maybe something similar happened to you?

(Fortunately I have had more than 1 backup)
