Those were moved to the new guy next to the Calamity Salvager. They are still available, but the list was getting ridiculous for a single NPC to sell everything.

I still want those items to be stackable in the Armoire, but it has lower priority for me because getting them back is fast and easy.

Putting together a LotA set however means eating long queues and hoping for the luck to get all the pieces. Which is why I'd like to be able to store then in the Armoire so I can get them for Glamour.
