In the original game there is a 17% chance of spawning an artifact for every artifact spawn place during a blowout. Also you can't abuse sleeping feature to spawn artifacts. This fix allows you to do it and also increases artifact spawn chance up to 95% or to your own. Now you can become a real artifact hunter. I DON'T KNOW WHY BUT DURING A BLOWOUT ARTIFACTS RESPAWN ONLY ON MY OWN LEVEL (MAP)!
