So I contacted the other mod about it ( https://mods.factorio.com/mod/Atlas_NormalOresForAngels ), but basically with RSO and it (and Angels, obviously) installed, enabling copper, iron, or stone makes them still not generate, and runs the chat message about missing configs
I was wondering if there's anything that could be done on your end, as that mod hasn't updated in 2 years and none of their other mods have either?
