I really, really like this plugin. I truly do. However, I cannot recommend it in its current state. Due to how the plugin handles mob spawns, it puts an insane strain on your server due to the issues with 1.14 and chunk loading. Therefore, your TPS will suffer unless you have some godly set up. If you are using this for another version it is fine, but not for 1.14. Other notable mob creator plugins do not suffer with this and that is why I cannot recommend it at this time.
