Guild Wars 2

I tried to make the recipe for the Box of Rampager’s Draconic Armour in the mystic forge using:

20 Crystal Shards – 5 Bottles of Elonian Wine – 50 Mystic Coins – 1 Rampager’s Draconic Coat (Exotic)

Except the Coat becomes greyed out, and when I just insert the Coat the option to make the recipe is never given.

Server: Sea of Sorrows
Guild: Tyrian Inquisition
Tag: [TI]

Problem occurred as of the patch on the 19th sept. Guild panel shows i am the only member of my guild, and tags are also empty.

I can also say that I am having this problem.

From my experience I had the same problem, but I found a fix. Like Jeffrey said, I moved back along the dirt road (a different route than the one I took to get to the cave) quite a distance, then moved towards Trahearne again and the quest continued.
