Description

message below is reported while kicking someone in server console:
[space.arim.libertybans.core.env.AbstractEnvEnforcer] Attempted to send plugin message to CraftPlayer{name=darkshabby}, but it could not be sent. This suggests you enabled 'use-plugin-messaging' but are not using a network. Please address this critical security flaw immediately. It leaves your server vulnerable to clients spoofing the plugin messaging channel.
but i am really using velocity(Velocity 3.4.0-SNAPSHOT (git-1db8c8c6-b458)) and followed https://docs.libertybans.org/#/Running-Multiple-Instances to install this plugin
