My previous Bungie Name was Clamnex, Rhulk's Art Agent#0755. My current Bungie Name is adept_brain_timelost. I completed a Solo Flawless Zero Hour on February 5, 2026 and a flawless duo Zero Hour on February 8, 2026 (both attached). The Team Flawless Zero Hour triumph has never unlocked on my account, even though both members of the fireteam finished with 0 deaths. My Bungie Name change occurred after these completions, but I understand triumphs are account-based. Could you please investigate whether this triumph failed to register?
