Hey there. Back in Episode Revenant, an objective mistakenly referenced (and worked with) the Dungeon-exclusive exotic Icebreaker, instead of the season pass exotic, Alethonym. Bungie's fix was to reduce the amount of ranks needed to reach GR7 by one. That let people finish that objective if they had Icebreaker, or ignore it and complete the others. This reduced requirement however seems to still be active in Episode: Heresy, letting us reach GR7 by doing all but one of the objectives.
