Well, plot resetting only works when a villager is moving in, and it requires placing patterns everywhere. (Because they won't move where you have patterns). I don't want to move my villagers out because I like them, but I don't like where they are, so yeah, I hacked. I also hacked to move my rocks around my plaza. I don't do it for items, though, as I did that for my previous town and that ruined the game for me.
