World resourcepack with other plugin compatibility

[Naarwhall]

Hello I have seen your plugin download on spigot and have downloaded it to be used on my server, however I have restarted the server and I do not see the plugin folder. I have worlds made using the multiversecore plugin. Is there by any chance that it is not compatible with the multiverseCore plugin which is why the plugin file does not load?

Additional info: It’s a 1.16.3 Bukkit server
I do have viaversion also
