Duplicate Items Rewards from Story Quests
Duplicate quest item rewards on Sith Inquisitor (Balmorra). Instead of getting a full set of armour from all the available quests in the area, including the entire 'Return to the Front' chain, two chest pieces from the same set were given. The only missing piece is the headgear from the Tarnished Force-Lord set. Since there's no way to access direct customer support even outside of the game for a Preferred account, this is the only place where a bug could get reported and fixed after much effort. Not encouraging new players to subscribe if continuous maintenance/fixing is not a priority.
That there are duplicate items in quest rewards is how they always have been set up since designers do not expect players to do every quest.
I believe the Tarnished Force-Lord's Headpiece is also a craftable item if that helps
