Removed load: STARTUP from plugin.yml, as it caused issues with Spigot 1.13.2 and potentially some other older versions.
Since the check for whether or not players are vanilla-banned is no longer done repeatedly in an asynchronous task, it is now only done on startup and reload. This means that the output of /balancetop will not reflect changes regarding vanilla-bans until a plugin reload or server restart is done. This is irrelevant if you use LiteBans or you have the settings.baltop.include-banned-players configuration option set to true. I may try to come up with a better solution for this in the future.
