CHILD OPTION OF DestroyInvalidShulkers
This setting will detect shulker boxes on the ground with bad metadata when your players attempt to log in. This protection works with the DestroyInvalidShulkers protection in case a malicious player has dropped a bunch of bad shulkers on the ground preventing players from logging in.
THIS SETTING WILL AUTOMATICALLY DISABLE WHEN THE SERVER RESTARTS IT SHOULD NEVER EVER BE LEFT ON LONG TERM. ONLY ENABLE THIS IF YOU KNOW YOU HAVE BAD SHULKERS PREVENTING PLAYERS FROM LOGGING IN!
To toggle this option in game use the following command: /istack toggle CheckGroundForBadShulkerAtLogin
When enabled, this feature will turn itself off whenever the server restarts or the plugin is disabled, it is only ever intended to be used for short periods of time.
