Bukkit

What steps will reproduce the problem?
1. Update to 1.8
2. See untextured purple/black block instead of book.

What is the expected output? What do you see instead?

- Hopefully there'd be a way for the item to still show a book.

What version of the product are you using?

- 1.15

Do you have an error log of what happened?

- There are no errors and otherwise the plugin still runs perfectly. The untextured book can still be read in hand, worked on, and books placed into bookshelves still read perfectly.

Please provide any additional information below.

- Love this plugin, the bookworm books are how our server stores its past. It's not game-breaking but the lack of book icons does ruin the immersion a bit.
