    I have an issue where when I start my server I get an error where my custom .yml file can't load- the strange thing is it only occurs on startup and if I type /reload then there are no problems whatsoever.

    Here's the error log:
    Code:

    And here's the actual code:

    Code:
    public void setupMaps(Plugin p) {
        if(!p.getDataFolder().exists()) {
            try {
                p.getDataFolder().createNewFile();
            }
            catch(IOException e) {
                Bukkit.getServer().getLogger().severe("Couldn't create maps folder.");
            }
        }

        mfile = new File(p.getDataFolder(), "maps.yml");

        if(!mfile.exists()) {
            try {
                mfile.createNewFile();
            }
            catch(IOException e) {
                Bukkit.getServer().getLogger().severe("Could not create maps.yml");
            }
        }
        maps = YamlConfiguration.loadConfiguration(mfile); // <- Here is line 173 for reference.)
    }

    @feff890 I think that you need to serialize the locations yourself, don't think that you can get Location lists.

    Ill try that and see if it fixes the error, but then why would it work on /reload ?

    Did you check the file after the reload?
