I know what you mean; these zombies can’t hear you walking around ten meters away at night, but they’ll come trampling after you en masse if you so much as sneeze in the middle of an isolated forest. I just started a new game as a sheltered character in an LMOE. I grabbed some supplies, walked through the forest to a nearby normal shelter, entered, and closed the curtains. I killed two zombie dogs and a zombie wolf on the way to that shelter. A couple hours later, I open the curtain, and there’s a horde of zombies outside and coming from the forest. As it stands, the spawning system is unusable to someone like me who just can’t fight off an endless onslaught of enemies 24/7 even when in the middle of absolutely nowhere.
