    Barking_Squirrel Could it be
    Code:java
    1. plugin = instance;

    instead of
    Code:java
    1. instance = plugin;

    Barking_Squirrel You are getting a nullpointerexception on line 22 of your tablistenerjoin class. I need to know what exactly is on line 22 to attempt to figure out why it is null.

    mind explaining why you think it NEEDS to be like that? Because it makes no sense that it NEEDS to be private and NEEDS to be final

    because private just basicly hides it for every other class except the one it is in.. and final means it cannot be altered. so it doesn't change anything with his issue

    You obviously didn't test what he said.



    but however. It throws it at Line 22. It should be already throwing it at line 20.

    You're sure that the StringList Slytherin exists?
