Hi all,
Been working on several missions and never actually came across until now. I place a Zombie Spawner Module and fill in all the spawner functions mainly to focus I'm talking about the activation say 500metres by blufor present.

When a blufor comes in range like magic it works however if blufor leaves the area before killing any or all zombies the zombies despawn and when the blufor comes back in no zombies spawn.

Is there a way to get the spawner if it doesn't to be a spawner so that obvisouly it spawns zombies in the area when triggered and despawns them when the area is empty BUT then respawns them when the area is entered again?

Or are these zombie spawners just for a one use item??
