Stuck Entities (Major) | On some servers it could occur that entities were not removed correctly trapping players and leaving behind particles. This could result in a number of exploits/issues and has been fixed. This only concerns 1.13.x servers.
Flight Fix | If switching between flight enabled/disabled or survival/creative it could occur that your flight ability was disabled. This has been fixed and no longer occurs.
CleanUp Fix | A missing check could result in an NPE when checking chunks in a non-existent world.
Improved Commands | Prior to this update all commands were only executable in-game. This update allows you to use the help command and reload command from the console.
Huge shoutout to @mibby for taking the time to test the plugin and find the cases in which the bugs above occurred
