first liveries dissapear now upgrade parts are vanishing?!?!?!?!

it is bad enough all my cars keep turning grey, but today my upgraded parts started disappearing, custom wheels, suspension, everything, even after repurchasing them, if I make a change the parts revert to stock and the purchased upgrade parts must be repurchased again,
I think this is the nail in the coffin, hours spent designing paint jobs that disappear, hours spent grinding to buy upgrades that disappear, hours spent building cars that don’t look or drive the way you want them too, at this point, what IS the point???
