Bungie have acknowledged that the SIVA Key and Sigil of the Young Wolf Emblem issues are both present in Destiny: Rise of Iron– and while the new patch released for the title does not quite addressed them, Bungie did promise that they were looking into them.
The SIVA Key issue sees Keys created by combining fragments forwarded to the Postmaster, even when the player has enough inventory space to keep them on their person. The “Sigil of the Young Wolf” Emblem issue, meanwhile, impedes the player’s ability to unlock the Emblem, or to gain the Student of History Trophy/Achievement.
Both issues are being investigated, and will hopefully be addressed by one of the coming patches and updates for the game. Destiny: Rise of Iron is available now on Xbox One and PlayStation 4. Destiny itself is also available on PS3 and Xbox 360, but those versions were not upgraded to Rise of Iron, and are no longer supported with active updates, beyond weekly rotations and resets.
