I thought briefly about an area reload command. Then when I realized what a disaster it would be to get rid of all the things like mobs and objects and players... ugh. Would be something you'd only want to do on a proto zone, not an installed one.
But then of course you STILL need to clean the pfile, god file, their range pointers, the area's vnums, all of this without damaging existing things they want to keep.
Heh. In the end, it's just simpler to do some things by hand
