Via CE Editor i placed a few Z spawns on "Alcatraz Island" (on my Deerisle Map).
I placed Dynamics and Static ones.
Problem: No single Z spawns there.
To give it a further test, if max limit was just hit, so i removed 80% of all other Z spawns on Deerisle.
Still no single Z Spawns on Alcatraz.
Additional Info: Deerisle map is at 16384x16384
Alcatraz Island is located at about: 15757x4824
On the attached screenshot
- you see (with enabled ESP) no single Z on that island - Even NO Zs on the dynamic HeliCrash.
- the reduced zombie_territories.xml, with the marked Z Spawns on that problematic Island
Seems the engine avoids spawning anything on that particular location.
