Buying all cars unlocked it for me.
Same here on pc.
My nephew played and wanted to change the order of my super cars.
Now both bought supercars and both safetycars are gone.
Got this myself. Unlocked the Ferrari Tributo, decided I wanted to have it in my main area and put my existing Aston Martin somewhere else.
Went to the Aston and selected "Remove Car", assuming it would put it in a safe place, went to Bay 1 to select the Ferrari and found both cars had completely disappeared. Can't even re-unlock them.
I'm assuming the only way to fix this would be to reset my save, but I'm scared of losing other stuff now to be honest. I haven't started a career yet, just afraid of losing pitcoins and Champions Edition benefits, because if THIS can happen, then...
