I registered my IRecipe instead of a stick recipe, but in the recipe book it's empty, the stick icon itself is there.
As you can see in the screenshot, the recipe icon is there, but supposedly I can do it, although I have no resources. When you click on the crafting icon, there is no reaction.
How to make a normal recipe in the book?
