Bug/Glitch with R8.

Had a fully setup R8 with the modified parts that the game allowed for me to add previous to unlocking any wide body kits for the car. Said widebodies got unlocked and I went for a touch up and a different look in the car and it crashed my game and when I loaded back in my R8 was completely reset off all upgrades and cosmetics, including air suspension and all vanity items. Now I’ve tried at least five times to put my car back together the way it was and not only are my parts tab completely glitched but my handling setup screen and ride stance screen are nonexistent. Please help. When I try to click on any of the parts that have the tires thumbnails it crashes my game to so I’m stuck unable to bring my R8 back to its former glory.
