while playing online I experienced a visual bug while customizing a car. i changed the body kit on the lotus exige which caused the tires to be sunk into the car.

Then when i switched to performance upgrades all the parts showed tires(shown in attached file). When I clicked on one of the parts my game crashed.

Now while on the home screen before i click online, the preview of my car is very bugged/glitched (shown in attached file)

when clicking to launch online mode my game gets frozen on the green and black graffiti loading screen.

After speaking with EA help and following all the troubleshooting they provided, they could not figure out a way to resolve this issue and directed me to the forums.

I believe that the game will not load the online mode because of the bugged state of the car. 

EDIT: I got the game to launch online mode by removing the save file. So I believe my theory was right and the bugged car is the problem. I have 65 hrs of time played and dont want to have to start all over again so hopefully this issue gets resolved soon.
