NFS Unbound - Car reverting Tier?

11/28/24 - Ive loaded up NFS Unbound, purchased myself a Corvette CS and upgraded all parts. (Single Player) Upon exit from a garage with my 400+ S+ Corvette, I decided to make some handling tunes. While editing my sliders, the tier of my car suddenly went to 317 S tier. Found it strange, I saw it happen to my Porsche GT3rs as well. All elite parts - suspension and trans. Help???

Attached files (if visible) are proof of the issue at hand. It happens randomly, and upon entering events the car will be the incorrect tier. Performance also fails when the random bug decides to change the cars tiers.
