Cars are instantly destroyed on spawning?

Only tried so far with the Covet and 200BX but when I spawn a car in, or I hit "R" to reset, the wheels all break off and the model of the car breaks and becomes undrivable. Is there a quick fix? Tried verifying game files on Steam and it didn't do anything.

I had the game installed and working back in Dec 2015 but got a new hard drive. The game is now installed on a different hard drive than my operating system, if it makes a difference.

 

Delete the folder in your documents titled 'BeamNG.drive', this clears the cache and removes any mods

 

Thanks, makes total sense. Works great now!
