All people who downloaded and used Version 2.1.0 of this plugin. Please clear your WildcardTokens table, I messed up the migration and now the Tokens table is pretty much unuseable.
This update fixes that migration meaning all people which update from 2.0.X to 2.1.1+ will not have this problem
Currently players were not kicked from a Spigot Server if they were not on the "whitelist". This was fixed by importing the correct EventHandler annotation (sadly I imported the wrong one x.x)
