Guild Wars 2

I wanted to buy now all recipes that were introduced with the living story “Escape from Lion’s Arch”. I could successfully buy the recipe for the Maintenance Oil Station from Evon Gnashblade and the recipe for Gift of Blades from Miyani. But it seems that the recipes for the Sharpening Stone Station and Tuning Crystal Station aren’t available anymore as Urmaug doesn’t sell the first one and Ellyna Graidy seems not to be at her location anymore. Does anybody know if these both recipes are still buyable somehow or if they will be introduced later again?

Ellyna is at the new graveyard but AFAIK she doesn’t sell the station recipe anymore.

This is bad as I want to collect as much recipes as possible. But as I haven’t played all the time this temporary content can get really tricky.
