Human Factors
Aircraft was being operated by the Ground Control Station at the AFB. The aircraft had an operational mission that was used for the transition from RDR to FHU within the FAA transitional COA.  The weather deteriorated at the destination; so the aircraft was turned around to return to RDR.  Upon turning around the operational mission in the aircraft was updated and the aircraft started a turn back to the south. Upon noticing the route deviation; the incorrect routing programmed into flight management system and the aircraft turning; manual control of aircraft was then taken to get back on route. ATC notified the deviation of the aircraft and the aircraft was already going back in the correct direction.  In order to prevent the same deviation from happening the missions sent to the aircraft are verified further upon returning to the home station.
MQ9 pilot reports turning the aircraft around to return to base; when the original mission is canceled due to weather. When the operational mission in the aircraft was updated; the aircraft started a turn back to the south. This was quickly detected by the pilot and corrected manually.
