But now they are living in paradise, with millions of purified liters of water produced each day, oppulent homes and powered structures with actual beds, you know - garden of eden relative to FO wasteland - they still cant wash their faces. Some settler faces have more, oddly the women seem to show more dirt on faces.
What I'd like is a mod or base feature that turns settlers from grimy to clean as settlements build up infrastructure. Or just a toggle to mass remove dirt marks from all settlers soon as they become your settler.
