In my spawn room, I have a barrier and a ground spawning zombie. I have path nodes everywhere but when both zombie spawn, they just sit there and do nothing.

Secondly, once you buy the door out of spawn, the zones have to wrap around the building. This causes me to have multiple of the same zone which I don't know if all of them are part of the same zone, or only one of them is working and the rest just do nothing.

Make sure you give correct KVPs on zombie target and zombie spawners also make sure you give correct KVPs for zone. Also you have to add line of your zone in your map name.gsc file. I am sure you can find some tutorial on youtube.

The Adjacent zones are set and the KVPs are good.  Edit: When I start the map I get an error message that says I'm missing zom-dempsey.iwd and some other zom-dempsey7520750fuji034h.iwd stuff. Edit 2: I fixed the problem, I had overlapping path nodes.
