Guild Wars 2

How do I unlock the Crusader’s Pack collection (basic collection). The notes say "To Unlock: On first completion of the story step “Prisoners of the Dragon” choose one of the three order-themed backpacks."

I have done the story instance, and received the reward (I chose the Initiates Backpack), but the collection is still locked. What am I missing? How do I unlock it.

All 16 chapters have been completed for Heart of Thorns, I even redid the Prisoners of the Dragon story again, but nothing changed. Do I need to have all the achievements done to unlock it? I only have 12/18 for the Heart of Thorns Act I mastery.

Thanks

You have to unlock the Vigil version. You unlocked the Priory (Whispers?) pack collection. You need to take a fresh alt through the story to do Crusaders (and a third for Whispers(Priory?)).
