so when you do the command to block the item from beiing crafted along with setting the item to false in the config it wont allow you to craft the item. but when you restart the server you can craft the items again.. not sure what i am doing wrong.. 

Hey Bushcake make sure you have your the following set in your config:

  "Save commands to config (save config changes via command to the configuration)": true,
  "Enable advance options": true,

ahhh ok, issue solved!!!
