Strangest bug to date?

Hi, I just encountered a bug that I never would have even thought would exist, take a look:

Yes, that is the arm for the engine testing thing.
For some reason it follows me around when I rotate the screen, just stuck in the middle of the screen like that.
From what I can see, it seems to be caused by if you load an engine which uses exhaust bypass valves in the 1960s or something (from an old patch) the game can't load it because in newer versions bypass valves come in somewhere around the early 21st century. If you press "Ok" through the countless error reports it will finally load a buggy engine and once you press the "X" in the top right to go back to your car, this bug will occur... if that makes any sense.
Tell me if you need more info or something, this bug isn't really that big of a deal because it only occurs when loading old engines, which most people may not even have at this point.
