In this final side mission to the new DLC, after killing the Hunters and the Harvester which is the main objective, to complete mission you must loot the Harvester. I have done this , gained the loot and do not get credit for completing the mission. Icon remains above harvester after you loot it. I then reboot the game and the mission respawns Harvester to kill it again and loot, still no credit for completing mission. Did this a total of 6 times, same result. Any ideas?
