Starting to look into FTB Monster which is the 1.6.4 succesor of FTB Unleashed. So with that comes a world reset. And to make things simple from now on I will only look for residenced areas when doing world updates.
Another thing I will be looking into will be bringing back the Monster Apocalypse bukkit plugin. So with world resets, the new, meteorCraft mod and mobs that will explode, corpse pile, destroy blocks and make dirt paths to get to you it is in your best interest to use the Residence mod and protect your property.
