So if I understand correctly, are we supposed to consider the items from the Contraband and Bounty rep vendors (Thana Vesh set, Mask of Nihilus, etc) as the ones that are "bugged" since they do unlock those items and complete sets on the Collections?
None of this is properly explained anywhere man, which is what leads to these frustrating and unfair situation. People spend their time and money on this game and sometimes their investment is not treated with the proper respect.
I've unlocked the Aratech Nethian vehicle from 1 of the reputation vendors on the same day I purchased the Marka Ragnos set. That one works but my armor doesn't. They have yet to reply to my in-game ticket.
