I learned a pattern called Redguard Mat, Mirage which I got from the Hlaalu Furnisher's Document. When I first learned it the pattern showed up when I went to the clothier table but has since disappeared. I spent over a week in emails with customer support proving that I had learned the pattern and was then directed to this venue. I have attached a screenshot showing the pattern as learned. I am afraid to spend more writ vouchers on the Hlaalu Furnisher's Documents in fear of any patterns, blueprints, ect. doing the same thing.
