There's no missing recipe, this is an old recipe file that was removed a long time ago. I'm not sure why it's still present in your instance, but there's nothing to fix since the file it's referencing doesn't even exist anymore. If you're an an old version of Consecration, you could try updating. But regardless, it won't have any tangible effects on your game.
