Whenever it transitions into night, the stars appear and it shows the full nightsky in all its glory, but a few minutes later the textures disappear and it becomes just a dull black with the clouds. Is this fixable, maybe reinstall the game?

Thats how it is on PS3 no way of fixing it i have that problem too

Damn, the nightsky looks so great when it works. Oh well, I'm still loving this game anyway.
