Hey, A troublesome little bug indeed. Momentum helmets that were previously available from Amanda Holliday cannot be reclaimed at the Holiday kiosk. I am aware that these helmets require SRL rank 3. However they are also bugged and require completion of the SRL VOl. 1 book. I have completed the book. Hence why Amanda had the items available for reclamation during The Taken King. Since being added to the Holiday kiosk in Rise of Iron, they are now unavailable and I am very sadly not able to complete my Momentum set. Dear Bungie, please fix, so I can look like a Christmas tree for Christmas! Thank you!
