Have you done all of them in this season?
A clannie was complaining about not getting it though beating the times that someone had listed. Out of curiosity we had him redo the ones he did in previous seasons, which had him obtain the emblem after the last one.
After spending hours scouring the internet for answers I do believe that I found the issue. My corrupted time was correctly fast enough on destiny.report but was not as fast as my two teammates previous season times. They have it almost 2 minutes faster so hopefully corrupted comes around again, but as always my fate is up to chance with only two weeks left until its vaulted. Sad day. I spent so much time on this damn emblem only to watch it slip away.
