It works, but if you have a world missing when the plugin loads, it'll spam your console with "[WORLD] is not a valid world. Check your settings.yml"
No infomation, no plugin name, nothing. I spent a good few hours finding the issue in my server because of something that the dev could have done in a few seconds! (Add "WorldRatiation: " to the log string)
Might change to a 5 star review when this is changed, as it is a good plugin otherwise!

Good plugin! :3
