Due to some servers using other methods than a #shutdown command to reboot and update I made this fork of the code to save the config whenever a tree is cut, not sure how this will scale to a large server, so use at your own risk, might look to have it save on a timer in the future saving a few minutes before the hour assuming reboots always on the hour...

Save suggestion was from MastaHiggins, thanks for that!!

Have packed my code in to my server pack and is working perfectly.

I'm not publishing as a separate mode as I can not guarantee I will maintain it, but welcome to use in your server mod if you want.
