Triumph > Lifetime > Cooperative > Nightfalls > Master Started playing in Shadowkeep, but didn't really do endgame PVE stuff until Witch Queen / Lightfall -ish. Over the last year, I've dived further in to the game, and have been going for triumphs in my free time. I saw this uncompleted one in the Lifetime section, and all it required was to "Complete a Nightfall on Master Difficulty". Easy Enough, got into an LFG, complete it... no triumph. Tried it again later on... still no triumph. Am i being stupid and wasting my time? Was this sunset similar to the "Defeat wanted Combatants" one?
