The option recommended by Rangel12 was added
- New option in the configuration where you can write the worlds where interactions with the npc will be disabled!
To apply this new function, you must delete your config.yml file

- It was also added the function that when interacting with an npc, it will look at you automatically, at the moment it only works for the npc that are not looking at you.
In the same way, if you are already using this plugin, I recommend that you delete your language files so that the correct ones are loaded again, 'messages_es' and 'messages_en'

Working for more!
