Pre-Searing Armour

Clearly, they've fixed the problems with (e.g.) Elementalist Robes not being in Pre-Searing. The question is: who the heck are the Collectors for the previously missing items, and where the heck are they?

I heard they were listed in the Prima guide, but couldn't find any more info on it than that.

#edit: in answer to my own question, for future reference, Hatcher (Fort Ranik / Regent's Valley (near Bear Hunters) ) now gives out the Elementalist Robes in exchange for Unnatural Seeds.

Since there are other missing items out there, if you find their Collectors, say so here.

Also, perhaps this update has had some effect on the elusive nature of the Tapestry Shred quest?

Hatcher also exchange Mesmer vest now.

I saw some poor soul last night trying to buy the upgraded Elementalist armor pre-searing.... I didn't hang around long enough to see if he actually did.
