    First of all sorry for my bad english skills.

    My problem is that I've programmed a worldmanager, but every time I've created a world and my server is restarting it's not there anymore for the server as world, just as a folder. I don't know how to fix it. If it helps, here is my method: https://pastebin.com/Lu3FqFrx

    Thanks for every help <3
  2. I don't know how your plugin works but do you load all your worlds on the restart? The server just loads the main world when starting. The others are just folders until you load them. (As far as I know)

    Everytime you shuts down the server the worlds get unloaded, when the server comes back up the only worlds that are loaded are the overworld, the nether, and the end. Every other world needs to be manually loaded by a plugin.
    What I would recommend doing is, everytime the command is run, add the world name to an array in a yml file, that way all of the custom world names are stored, and in your onEnable() method you would just loop through them and load them with something like this:
    ArrayList<String> worlds = getWorldsFile().getList("worlds");
    for (String world : worlds) {
    WorldCreator wc = new WorldCreator(world);
    Don't worry it will not delete the world and put a new one it will just load the world!

    (Of course getWorldsFile() should be defined and return the yml file. If you are not experienced with custom yml configuration files I would recommend checking this https://www.spigotmc.org/wiki/config-files/)

    @leluckyyDE Hope it helped, Robert.

    @robertlit Thank you but why it doesn't work with Bukkit.getWorlds().add(world);

    @leluckyyDE You misunderstood me.. This obviously wouldn't work because adding a world to an arraylist won't load it.. What I meant is that everytime the command to add a world is run you will save the world name in an arraylist inside yml file and then in the class that extends JavaPlugin in the onEnable method you will load them (see example in previous post).. Do you know how yml files work and how to interact with them via bukkit? (If not check the link in the previous post)
    If you have anymore problems @ me :D
