problem with the darker nights

[jayhova]

I have been playing with darker nights for a while now. I tend to have things set on about 50% brightness as it makes things a bit more realistic. The problem is the transition between night and day is no longer smooth. It seems a straight negative number is applied rather than a deeper light curve. The total negative should be added gradually up to the darkest part of the night. This way there's not this sudden jump in illumination at dawn and dusk.
