I remember about a year ago they stated that all recipes you had been rewarded from a quest, or ones you had created, would be permanently saved (not just the last 8 or whatever it is now). Since then, I haven't heard anything indicating that this is still a plan, though it would be really handy and provide something to do in the meantime while content is being added to the game. Am I overlooking something, or have they scrapped this idea entirely?
