Bungie tweeted that the clan xp milestone is still bugged on turn in, but if you hold on to it till next reset, it will automatically decrypt into a powerful engram! Save it! https://twitter.com/BungieHelp/status/996453899576881152?s=19 Update: I wish they'd have something like in World of Warcraft where if there is some sort of bug like the Rat King or current Clan XP, they could send a text letter to your postmaster for you to read!
