Variants:
1.) When holding click (like it asks) to get extra info, your skin (specifically the face) glitches out.
2.) When spam clicking the item in the "book" repeatedly (including shift), you duplicate the recipe items.
3.) If you only use 1 item in the recipe, it has the "cannot craft" red highlight.
4.) While holding click (like it asks), hovering over an item, and then pressing shift, the output disappears.

I am looking for more bugs, so I might come back and update with some extra finds.
