Hello - The plugin is good, however you can code your own with skript (as most people in the community have done).
and others.
If a staff replies and answers, you may have the plugin added.
Maybe just add something like "this server can only run on **blah blah blah** version, as this plugin is not on 1.15.1. So the ViaRewind plugin is needed."
Also don't necropost. Someone lock this. (Thanks)
