I've watched terminators video as well as others on Youtube and I've also read the Wiki. I haven't mad a map in a while but i did make a few practice maps right before I started working on this one, I have exhausted every way I can think of to fix this and so I'm posting this as a last resort.
So I had two zones, "start_zone" & "hall_zone", they both worked perfectly, then I built up my map some more and added in the zones, stupidly I called one of the new zones "hallway_zone", so I won't get confused renamed "hall_zone" to "lobby_zone" and changed all the relevant KVP's and edited the mapname.gsc. This broke the zone, no zombies would spawn while I was in "lobby_zone (hall_zone)" so I changed it back. Zombies now spawn again but the game will now freeze once for a second while I'm in that zone (as seen in the Youtube video). I also can't get the other zones to work, if I'm in them the zombies won't spawn at all unit i re-enter "hall_zone".
Note: When I changed "hall_zone" to "lobby_zone", the text at the top left of the screen when I started my map still said "hall_zone" and that it had no volumes or spawners, renaming it back to "hall_zone" """FIXED""" it.
