FAQ
Q: Why does the map show up on the cartography table, but not in the crafting table?
A: Due to limitations in the API i was not able to remove the recipe from cartography tables completely, but they are still blocked.

Q: How do i disable the error message when trying to clone a map or book?
A: If you take a look at the plugins configuration file, you will find an option named "Notify-users". Set that to false instead of true, and restart your server.

Q: What if i only want to block cloning on specific maps or books?
A: This can be done with an upcoming plugin i am creating.
