Rewrite the scroll fog shader slightly. Scroll fog is a 2d layer, it has no depth, or can be considered to be drawn at infinity, therefore is not effected by the viewport light. The scroll attenatuion value also I think attenatutes the scroll fog alpha value. This fixes various effects in emergency call ambulance.
