1. The book for alexs mobs has all white text and is therefore unreadable. I have played with alexs mobs befor and this was not an issue.
2. The book of bees was uncraftable. I tried to craft through the mixer and a crafting tabel.

Alex's Mobs has been removed from the pack long ago. Pleas report to their github below
