I just noticed quite a few flats open up on N1. It looks like this was more than just inactive players being cleared. It looks like quite a few NPC's were removed (thankfully not 5's or 10's.) Is it possible for Evony to explain the methodology/selection process for clearing flats? Obviously, we use them defensively (build NPC's adjacent to your cities so opponents can't do there,) but also for farming. Please explain. Thanks!
