Can't see anything in battle while playing as Chaos Dwarfs

I'm playing as Zhatan, and during battles, the light keeps changing between daylight and overcast, except that it's overcast to the point of darkness, and I can't see a bloody thing on the battlefield. I played the chaos dwarf lord near Imrik before, and I can't remember if it was like this, or if this is just because I'm in the northern wastes area of the map. Is every battle going to be like this?
