Hey @GibbletsnBits, thanks for reporting! It seems that the Ore Truck doesn't get stuck on its own, but something must have bumped it when it was harvesting inside the harvesting field zone, so that it fell out of the zone and thought it was still in the zone. The best way in this scenario to fix it would not to be to push it further away from the zone (toward the refinery), but further into the field so it finds the zone again. We'll make an adjustment so hopefully it harvests by default further into the zone and makes this less of an issue in the future.
