Re: Changing an areas vnums from inside the game

Unfortunately, it's not that easy..
You're going to have to move things around in room_index_hash and
stuff.  Otherwise it'll crash one way or another before long.
It probably crashes in asave because olc_save.c calls get_mob_index
and get_room_index etc a lot.
