I am beginning to get rather tired of this. Just yesterday, I made just over 100 Twinkling Scimitars. Today, I log in to make some more, and I no longer know the recipe. This happened two weeks ago with Sticher's Mittens. I have made all the mittens on my characters and sold at least a dozen more, and I log in to find that I know no longer know the recipe. And while I am on the subject. For the 5th time the same account has 'lost' the 9th ED upgrade. I have submitted at least a dozen total complaints/bug reports and either received no response or 'sorry we can't do anything'
