Spawn Pattern

I've been looking into this and it seems that the zombies should be spawning near each of the towns not just one. But with Nexon's inability to test their events after they have added them to the NA servers before they go live most of the town's are bugged and thus do not spawn (If they did you'd see a boss spawn notice). If you are doing the sketches head over to Emain as the zombies will spawn there every night either behind the pub or amongst the spiders near the advancement test area.
