I finished the Hearts and Minds story instance on a character who had chosen the agent’s pack as a reward in a previous mission, but I was not rewarded with the dragonvine whispers strap collection item.
I have the agent’s pack soulbind on the character, and it was in the inventory. I finished hearts and minds on the 2nd character and did not receive the collection item or have it become automatically unlocked.
I have finished the instance on one character and did correctly receive the item for the scholar’s pack collection, so it did work before.
I am afraid somehow it is now stuck on trying to give me the one I already have which is why I do not correctly receive the collection unlock.
