This one, as the title says, now adds support for 1.18! The plugin has now been complied against the 1.18 Spigot API.
This version also adds the players UUID into the lore information in the main PlayerListMenu.
If you discover any other issues with the plugin, please do send me a message or leave a post on the forum with your issue and I'll try my best to assist you.
