Warning! For this to work in 1.13 you need HeadPluginAPI 1.7.0-1.13 specifically. Otherwise the plugin will not work.
Warning! This version ONLY works in 1.13. Use HeadSweeper v1.4.0 if you want to use this plugin for version 1.12.2 or earlier (And use it with HeadsPluginAPI 1.7.0)
Other than that: have fun with using this plugin in version 1.13
