The problem with the armor level (Mad Max)

Hello to all the crazy roads!
Faced the following problem: lost armor!
No!, visually everything is in place, but suddenly you're getting cardboard and if you go to the garage in TTX 0 armor, or that give the emblem on the hood. Treated entrance in the armor section of the garage(have to remind the game: - Hey, watch it!) But after a certain period of time, everything is repeated!((
Who faced and is there any permanent treatment?
