Is the door solid? (Can you crash woth that part of the door?)
If yes, then its a really frustrating problem.
Otherwise its just a bit funny.
Sorry, i dont have a solution for you :/
Does it happen on every track or just Macau?
Did you mess with the files in the 'animations' folder? The 'car_door_R.ksanim' is responsible for the opening and closing of that door, but if you had just deleted it by accident the door should just not have opened in the first place. Maybe some kind of mod intended for making screenshots?Its transparent and won't hit other objects.
It happens on every track.
Anyways, I tried to check the integrity of the game files and it is fixed. However I still have no idea why it would happen lol
