My fireteam and I completed the Throne challenge in the Leviathan Raid today (01/10/18) in an attempt to complete the requirements for the armor ornaments from the Eater of Worlds Raid Lair. However, this is the only challenge so far that did not count as a completion even though we all got the emblem for completion as well both loot chests. When we took at look at our Eater of Worlds Raid helmet, the challenge for the Throne was still listed as a requirement. This is not true for the Gauntlet or Pleasure Gardens which we have completed as well (still waiting on the Royal Pools rotation). We believe the game has glitched on us... Please let me know if this is happening to anyone else or if Bungie knows about this happening. If it is only my fireteam and myself, I would appreciate any advice on how to correct this issue short of having to do it again... Thank you for your time and reading this post. I look forward to reading your response(s).
