Long story short, I've got a base that encompasses the entire airport in Altis, It's completely sealed off, but I've witnessed raiders spawning inside the base. In other words, I've got a 1500m Safe Zone module on it that isn't preventing raiders from spawning on/near the runways inside closed walls.

The Safe Zone module is also on top of a zombie blacklist module which is also 1500m, and is successful in preventing zombie spawns.

This is also a MP scenario if that means anything.

Any help and information would be greatly appreciated !

Also I'm completely new to all of this, this is my first experience of Arma, and I've spent the last 2 months learning Arma scripting, so I would ask we keep the verbage to layman's terms please lol
