    I want to store some data in my config file. But suddenly I have problems saving the UUID of the player. It actually always worked with Main.plugin.getConfig().set(Main.rentID + ".user", e.getPlayer().getUniqueId()) Now I try adding .toString(), but that does also result in user: !!java.util.UUID {} instead of user: the uuid of the player. I have no idea now. Maybe you do. You can also see an error log below.

    Code:java
    1. [18:32:39] [Server thread/ERROR]: Cannot load plugins\Grundstuecke\config.yml

    You're definitely doing something very wrong, if the .toString()-method doesn't work for you properly.
    It basically cannot return an constructor as the overriden .toString()-method itself does NOT contain anything like that:

    Just use player.getUniqueId().toString() and it will work, it did a lot of times for me already.
