One time use item removed hardcoded part the required to item to be a nether star. you can now set it to any material you want.

when right-clicking if one spawner was behind another it would take the right amount of items, but if you just right clicked once it would also take the spawner behind it. this is fixed in this update and the user must click again to remove the second spawner.

Please delete your current config.yml or change the & before color codes to #. You can compare you config to the latest if you have already made changes:
