It also includes comprehensive admin tools for server management, complete with console support, offline player compatibility, and granular per-world configuration.
⚠️ Required Dependencies This plugin is an extension and will not function without its core dependency:
GriefPrevention (Ensure you have a version compatible with your server software)
