Bug description: Once you unlearn a profession, you can start it over, but not completely. I can't redo the quests that i have already done, but i still have lost the rewards (recipes) for the specific profession. For example, i already did Enchanting's first quest (Some Enchanted Evening), decided to unlearn the profession and start over and now i can't redo it, or you can see that i don't have the recipes from the already completed quest. I can only continue with the next quests (The Last Few), that i have not done yet.
