This problem can be mitigated by adding a "calibrate" function in your software and binding it to a driver-convenient button or trigger on the joystick.

Whenever the robot's field-orientation sensor loses calibration, the driver can quickly rotate the robot to some pre-determined orientation (most likely aligned parallel to the length of the field) and push the button to re-calibrate.
