SO: I created a command (/statik save <world>) which saves a copy of <world> and can be loaded by using the commands (/statik load <save>). The save will still be available even when the world is deleted. Anyways, that's not the problem, and that ^^ works perfectly fine. The problem is though, that it checks if the world exists (when loading the save) and deletes it if it does exist. It then makes a new folder and copies the files from the save into that folder. Then it imports it using this code: Code: Bukkit.getServer().createWorld(new WorldCreator(args)); Now that, also works fine! But when loading a save of a nether world, it creates a completely new world instead of simply loading the already existing file! How do I fix this?
