    Again, to be in accordance with the Java naming conventions, that method must be "checkIfFirstJoin".

    Anyway, I don't see where you're doing the actual editing. I also really need to go to sleep, so explain that and either somebody else will help you or I'll wake up and do so.

    and i'm editing it in the FirstJoin class under where i called the checkIfFirstJoin() Method

    Also it's saving the /Core/playerfiles/Heirteir.yml correctly but it's just not changing the value inside of the yml file and i dont get why

    Is the plugin ever set to anything in PlayerFiles?
