Hi. I've just had to return to orbit from Expedition: Nessus because the event didn't complete. We escorted the vehicle through the 3 waves successfully. The diamond direction marker pointed is to where we started the mission. We all scooted down there, and as quick as a flash...nothing! No loot chest, no loot, not even an end to the mission. Despite the 3 of us scouring the map to look for...who knows what to try to trigger a completion we came up empty. One by one we returned to orbit with nothing to show for our completion
