How about a way to repop/respawn all entities in a loaded zone without having to restart the World (or wait for the zone to shut down)?
Also a way to reload the Commands lists, spawns, items etc without restarting the entire world? When I make changes to a zone (like adding commands), I have to restart the world to get those changes realized. Not a super big burden, but it would be easier and much more fun to stand in a zone and watch your creations pop to life!
What do you think?
