Cool post and exactly what Ive been looking for, its something id like to do for a new server setup, expecially seeing one player on the last setup decided to just go as far as he could, but also preloading the chunks just makes sense to improve preformance of the server.

I had a look at the Plugin, the first thing I see is big Red text "NOTE: This plugin is no longer being supported", and I notice it dosn't support anything past 1.14, any suggestions on how to do this on a newer setup?
