Bug description: sorry its my first time and I do not know very well how to do the report, but since I'm here let's go to the story.
I learned the profession of skinning, and I was wearing it, but when I reached the legion level I did not learn the recipe for a leather-only scales star,
so I unlearned the profession and relerendi because I thought it was a bug, but when I learned my profession and used the old recipe book, he did not teach me the recipe for scales I had already taken, and the worst of it is that I do not drop the item to redo the quest, I want the problem solved or that I Tell me what I should do to resolve it, thank you.
