I had a go at editing an XML file but I get occasional console pop ups and........all roaming zombies have vanished. POI zombies are there but it's a ghost town otherwise. I'd just like romero zombies roaming around, can someone either supply a vanilla .xml file or a mod that still works with A20. I recall there being a mod that did this for you, but no doubt it's outdated. Thanks - I hate dogs and breaks my zombie head canon :)
