This doesn't happen right away. It is after I have saved my work and come back to it. Always crashes on the page that I have used the Item feature.

So, I really can't figure out what is going on. I re-did the book without using the item feature. I am fine in game when I am creating the book. If I exit MC and restart the whole game, next time I open the book it won't let me past page 5. It seems to be always page 5. Here is the json file http://pastebin.com/Jn2dSr7s

Edit: So it seems any time I want to use the item or recipe function in my book it crashes the game.
