This has always worked for me in kits:
387 1 title:&a~_&dPirateCraft_Bible_&a~ author:GodsDead lore:Rules_Commands_Ranks book:Bible

But recently after updating to 1.11.2 its stopped working, If I rename it to:
387 1 title:&dPirateCraft author:GodsDead lore:Rules_Commands_Ranks book:Bible
Then it works, but I have no idea why its stopped working, there are no errors in console.

Works fine for me.

Please make sure the chapter Bible exists in the book.txt file under the Essentials plugin folder.

Yeah it does, Ive used it for 4 years, only recently its stopped allowing the name its always used...
