Hey there,
I'm playing on PC on the EU server.
So I had almost all the recipes, apart from the Dubious Camoran Throne recipe. I did have some double recipes, I figured I trade them.
So I traded with a guy called xpanko, my jewels of misrule recipe for his dubious camoran throne recipe.
I had the recipe in my inventory, double clicked to learn it. The top right of my screen said: You learned the dubious camoran throne recipe.
I waited and didn't get the achievement, so I opened my journal, the recipe didn't record for the achievement. I figured it was just delayed.
I traveled, nothing, relogged, still nothing. I went to the provisioning crafting station, couldn't craft it. Checked my inventory again, recipe not there.
Its not a such a big deal, but I think its not how its supposed to work. It sucks, because it was the last thing I needed for the event achievements, and the recipe is worth 10k atm in the eu server.
