Issue description:

I tried to setup the Auto-Anvil from Openblocks to combine two enchanted books of the same kind (2x Protection I = Protection II) with a processing pattern. The problem is, if I click on start during the crafting process, nothing happens (the button stays gray and nothing happens)

For the output I used a book (protection II) combined in an anvil, which got the following two nbt tags:
RepairCost:1
StoredEnchantments:[{lvl:2s,id:0s}]

If I use a cheated book without the RepairCost nbt tag the crafting process works fine!

I could reproduce this with only Refined Storage (version 1.5.32) and JEI (version 4.8.5.159) on forge (14.23.2.2625) installed, by using a chest (as a placeholder) next to the crafter instead of an Auto-Anvil. (for the screenshots I added Actually Additions, but tested it also without it...)

Here you could see the nbt tags of the working recipe (with the cheated book):

And that's the one with the book created in an anvil (with the RepairCost nbt tag):

There is nothing in the log file, but I've uploaded it anyway.

What happens:

Tried to combine two enchanted books, autocrafting doesn't work.

What you expected to happen:

Autocrafting doesn't hang there forever... 😄

Steps to reproduce:

1. Build some basic RS system to autocraft
2. Combine two Protection I books in an Anvil to get a Protection II book (also tested other enchantments, same thing there...)
3. Set up a processing recipe 2x Prot. I = Prot. II
4. Try to craft the book

Version (make sure you are on the latest version before reporting):

• Minecraft: 1.12.2
• Forge: 14.23.2.2625
• Refined Storage: 1.5.32

Does this issue occur on a server? maybe (only tested in singleplayer)

If a (crash)log is relevant for this issue, link it here:

(No crashlog, not really much information... :/)

Don't autocraft with enchanted books, it's not meant for that. RS specifically ignores the enchanted book tag so enchanted books work with other recipes.
