Hello, How do I make it so the world is not saved at all, and so when the server starts up or is /reloaded, the world will reset? Thanks
One idea would be to create a ram disk and then copy the server to it and run it from there. As long as you never copy BACK to the original server it should come back up as the "reset version" every time it copies to the ram disk and starts up.
You should also look into Multiverse-Adventure. Apparently it does this exact same kind of thing too.
