This is something we used to do and I think it worked really well.
The main world of TF I think should be regularly re-set and pre-loaded maps restored on to the server. I've been noseying around the MB World for example and there are so many great builds that could be put as part of an actual map, and used as a spawn overworld.
This is something that we used to do on TF back when we had Clanforge, and is something I was doing for a while when we had the temporary server, and people seemed to enjoy exploring new maps in the overworld.
We can now if we want to programmatically delete the overworlds coreprotect data, restore a map backup and make the old overworlds available to download if people want, and schematics are already persisted as well.
It feels like a good way to spice things up a bit, while still fostering an environment for building.
Any thoughts?
