Darkness Bug?

Hi all.. I´ve had this problem for a while, but finally decided to solve it...Sometimes, when I start a flight at day/dusk that runs into night, the light gets "stuck" at dusk and the "dark" night textures does not load... (It will eventually get totally dark in the sky, but that total darkness would occur around 01:30 local time at KSEA, this time of year, is laughable!It´s a little hard to explain, but normally you would see dark textures on the ground and on other objects/aircrafts etc.. In my case all that is not illuminated or a "lit up" texture itself, remains totally black.. (except some AI-traffic that gets its´ "normal" night textures, (a bit too light actually)).Check attachment:Stuck at dusk, and missing night textures. (Sorry about the lowres)Does anyone else have similar problems?P.S. The missing night textures is pretty good in one way: Outside any urban area, it is TOTALLY black, just like real life. Also the ocean is TOTALLY black, as it should be, but I´d like to sort this problem anyway. :)/Johan
