the whole npc prob would of been easy to fix just make it when a city is abandoned its turned back to a flat and only the creator can put npc on the maps, the main prob was that everyone hated how people were making cities around them then abandoning them and creating Fields of resources, they cant do that if the abandoned city turns into a flat plus it keeps evony less cluttered. i think creators need to keep a better eye on inactive cities, just about every town near me is dead
