gap .. just an FYI
I was in medium fog at 6 pm game time with either the sun just dropping below the horizon or the moon rising above it. I couldn't tell which one, because it wasn't visible through the fog, although the rays were there. I couldn't believe my eyes when I saw that I still have that gradient effect.
I'm going to have to just ignore it, because I'm too tired to track the problem down anymore, but I wanted to let you know that I didn't resolve the problem like I thought I did a couple of days ago.
