Guild Wars 2

When i and my 2 friends finished HOT living story, the recipe to upgrade plated weapons to machined (smth Core) did not apear in recipe list…so kinda those skins are blocked right now from getting at all.

after crafting – http://imgur.com/ot6awY7

so basically right now machined weapons are impossible to get because this recipe is bugged.
