Keyboard backspace key disabled if assigned to controller

[Michael]

If you assign the vehicle repair feature (backspace) to another input device, such as a controller, the keyboard backspace key becomes disabled and only the controller input will work. Example for Xbox controllers, mapped to left D-Pad:

COMMON_REPAIR_TRUCK                    JoystickPov          0 0 West
