Describe your issue

Check "additional information" for the screenshot showing exactly what is going on.

The book enchantments don't matter; it just has to involve stacked books (why can you stack enchantments?)... and the FIRST item has to be stacked.

This is not a crash - it's entirely item-based. Probably just a bug because of enchantments being allowed to stack, though... probably just how the game can't handle things too well and KubeJS having to "step in."

Steps to reproduce the issue

Make your anvil and books (that you probably found)
Attempt to put a stack in the first slot and any amount of books in the second slot
KubeJS complains.
Do the same, but 1 book to (at least) 2 books.
The extra book is strangely missing, resulting in... otherwise normal enchanted book.
