    @falscherIdiot You are not checking if there is a displayname, that can return null.

    @falscherIdiot
    e.getCurrentItem().getItemMeta().getDisplayName()
    That line can return null.
    So my advice would be changing the check with the hasItemMeta to also check hasDisplayName

    e.getCurrentItem().hasItemMeta() && e.getCurrentItem().getItemMeta().hasDisplayName()

    @falscherIdiot Please post your main class and your updated InventoryClick class. They are probably related.

    Your main in InventoryClick is empty.

    @falscherIdiot Your world is not loaded yet, so getWorld(world) is returning null.
    Your other error is because main is null in your InventoryClick class.

    @falscherIdiot Ylj are calling new Main(), don't do that.
    Use a constructor to pass the main instance along instead.

    i noticed that and removed that but now it has a problem with
    Code:
    main.getConfig().set("Spawn", p.getLocation());
                main.saveConfig();
    these two

    So I solved the Problem and everything is working fine now
    i needed to add
    Code:
    Plugin main = Main.getPlugin(Main.class);
    Plugin main = Main.getPlugin(Main.class);
