I'm currently trying to complete the Dead Orbit Rank 25 quest, but I'm having issues: The 'kill minions of the darkness' task has stopped at 66%, and the 'complete heroic strikes' is not registering any completions. the only information I can offer is as follows: 1. All requirements are met - shader/emblem/class armor is equipped 2. I do not have Rise of Iron yet. 3. I've been playing on the 'Taken King Heroic' Strike list. Is there a specific Heroic Strike I need to be playing to complete this quest, that I can't because it's locked out for not having RoI yet? Thanks for any help offered.
