This plugin now again works on the latest version of Minecraft, version 1.19.1!
Added a clear command! By using /dragon clear[player_name] you can remove all your/someone else's dragons in all worlds at once. This command uses the same permissions as the remove command, meaning you need petdragon.command.remove to use it at all and petdragon.bypass.remove to clear dragons spawned by other players.
Added new configurable messages for the clear command.
How to update? Download the jar file from the top of this page and put it in your plugins folder. Make sure to
remove the previous version of this plugin. Now
restart (not reload) your server and you are done!
