I completed the last mission "The Ritual" on Legendary mode, with a friend as the fireteam leader. We got the notification of the "Witch Queen - Legendary" Triumph completion during the final cutscene. When we were taken to the enclave on mars, I was able to get the Emblem from the triumph. But after that, I was logged out of the game. When I logged back in and rejoined my fireteam, my Triumph progress for "The Ritual" mission was gone, and the emblem was gone from my collections and inventory. My fireteam leader was able to get and keep his emblem and exotic armor (he got the Secant Filaments), and the other fireteam member didn't get any exotics from Ikora but he got the emblem. What should I do?
