There is a random error where my age books will randomly stop working for me (the host computer). Basicly i get the error bellow when clicking an age book on a stand or in my inventory. Not sure what causes but it gets quiet annoying so any help would be nice. I have to close and reopen the world to fix it for a short while.

Note: This only affects the host computer and nobody else. Does NOT crash minecraft.

Code:
