This script is very easy to use and very friendly with any version (above 1.16).
Using the command "/sk reload refound.sk" you will see some errors in the chat, don't panic, those are not errors, what will be said there is the fact that this script will "damage" a little of the maximum power of the server. That's all I had to say about this, if you want more information, you can give me a friend request on discord (Cheeto#8126)
