So yeah I ran into this little "low-rider" glitch where the claas body kidna detached from the tires and got really low to the ground. I couldn't drive forwards or backwards with this glitch. It happened after I had tabbed to another tractor and then tabbed back. I tried "respawning" it but that didn't help, I then tried hitting the "R" in the fleet menu(on the same line as the respawn button) and that fixed it, but yeah I guess it was just a freak glitch.
