I just ran the Leviathan Raid on Xbox One Via Guided Games. We were "Guides" in the guided games. 4 of us are in the Knights of the Night Clan, 1 was a friend, and one was a "Seeker" in the guided game system. After each raid encounter all 6 of us earned raid keys. Conduit, Armory, Aqueduct were the keys that we earned. After we finished the Calus portion we went down the elevator, earned our loot and then went straight back into the Leviathan raid without going to orbit. All 3 of my keys (GT: Evi1 Abed) were deleted. I have 5 other eyewitnesses to this. Not only this, but all of our "The Proving" Raid Challenges had 0% progress. I did not create a new character. I did not switch characters. I did not do anything. We went straight from Calus's rewards room (with all the robot Calus's) back into the beginning of the Raid.
