Strange problem with night texture

Hi everyone,I had this problem awhile back but thought I had fixed it as I was using ENB with an extreme dark setting at night. I have since backed away from such an extreme setting (moved the night darkening from 40 to about 25), but now I get this strange yellowish sky texture at night. See the (I hope) attached photo. I have searched for folks with similar problems but most inquiries were related to the darkness of the ground textures relative to the horizon, not necessarily a yellowish tint to the sky. Any help would appreciated!
