Ok heres the situation, we have several worlds, our naming convention is pretty hard to follow so i shall explain world (the default) world_nether skyworld (which is a err skyworld) pvpworld (different permissions on this world as its soley for pvp) worldold (used to be a main world now its a lootable world we want to make hostile) ok so we want to make worldold hostile, my first thought was to import it with multiverse as nether environment ....that did not work it created a new world so i used propertime to set it to perment night and using a spawnmob plugin placed a load of mob spawners about, to do all of the world would take me ummm more time then i am happy with what we want to do is have all mobs (preferably giants included) except slimes spawn natuarly on worldold but leave the other worlds untouched does anyone know of such a plugin or is willing to make one?
