Reproduction:

I tried to make the Codex Cicatrix with the rune, but it didn't react. No missing recipe notice, no failure, nothing. I used a fountain pen, a book and a dead mouse

Dead mice are objs, not mobs. Need a mob/living, a hide, or otherwise.

Not considering this a issue but I'll get a second opinion

Deemed not a bug, but no harm in making it so
