I, myself, am a fan of the sneaky style and I never leave the town. I have never had much problem on survival mode in urban environment including build 32 because of how easy it is to avoid zombies. If you are an inconspicous graceful burglar (ideally a gymnast too) you can sneak by almost all of the zombies and the few of them that actually spot you and chase you - you can easily either dispatch or outmaneuver. Not much else to say really, except that that build is rather nomad-like than anything else. But I have to admit, build 32 is the most challenging so far. I made the same burglar with 4.0 population and 4.0 multiplyer with zombies respawning every day. I managed to survive for 28 days before I stopped playing because I (the player) lost hope seeing the insane number of zombies. It was overwhelming and soulcrushing, feeling like the tide would never stop and there was no hope of survival...

Wveth, you have most probably left a door open. As it has been stated in the first post of this thread (woah!) if there is no clear (accessible) path from a random spot on the map to the desired spawn location, the zombie won`t spawn. Which is kinda a bummer because I leave the front doors of the houses that I have already looted open .
