If you complete a Mission in Ice Queen Lulu to unlock a new recipe by cooking enough of an existing dish, and claim the recipe in the main menu interface before you enter the actual Ice Queen Lulu minigame, you will not unlock the recipe. The new recipe will not show up in the Codex, or be available in the Cooking or Selling sections of the minigame. Furthermore, because the Mission associated with it has already been claimed, you are locked out of that recipe unless this bug is fixed.
