So as you know Minecraft has updates that sometimes causes new things to gen in the world, or some bukkit plugins add new rendering. So I was thinking, what if there was a plugin that would completely delete/restore the chunk you are in or a radius around you so that way they can gen with new qualities? I don't know if this is possible or if it's been made but it would be very helpful IMO.
Select a region and type //regen. Or if you want to do the chunk you are in, do //chunk then //regen.
