We loaded this mod onto an existing game, and tried it out. While we enjoyed the challenge we found it overwhelming for a large factory, so we removed the mod, and now all the Spawners are gone on the whole map. We have tried to readd the mod and even then the Spawners do not return. We didn't make a back up save, and we would like to save this map. Anyone else have this issue, or know of a way to fix it?
