In a few months ago I was searching exactly the same that you are requesting right now. I found this plugin ( http://dev.bukkit.org/bukkit-plugins/map-reset/ ) but now I think doesn't work right now because of UUID and outdated. :/ If someone remake this ... EDIT: I have found a similar plugin: http://dev.bukkit.org/bukkit-plugins/worldreset/
elkidz First plugin: UUID for a world reset plugin isn't an issue ( it isn't using uuid's ) And outdated is different then broken
elkidz I have had a look at these but they require a server restart to reset the world. This is why I want a plugin that can reset the world without a restart.
For any developer that wants to complete this: https://github.com/Huskehhh/EndRespawn -- There's some old code that may help (I hope?) Thanks, Husky.
