It's been over two weeks now and I haven't received the Marathon themed emblem from the reveal stream. The drop reads as claimed and completed on Twitch, at first I thought that I might have waited longer than 24 hours to claim it but, should that have been true, I don't think it would have the check mark and appear as normal. I contacted Twitch but then they said to contact the game developer. This is the best way I know how.
