I used the one-time knowledge point reset NPC to reset my inscription specializations on this character. All of my Algari Treatise recipes were (I believe) erroneously unlearned. I am aware that the game warns you that you will unlearn any specialization-learned recipes. Algari Treatises, however, are not learned through specializations. They are learned through discovery when crafting other treatises. This means collecting these recipes requires a lot of time, effort, gold, and luck.
Because these recipes being unlearned does not seem like the intended behavior of the system, I am posting this here to make Blizzard aware and hopefully have my hard-earned recipes restored.
