So, today, I wanted to go into my redstone world. I go into it, and I notice there's no sunlight nor sun. I looked everywhere. I set the time to 0, thinking it's night time, and then I can see orange and black lines in the "edges". My render distance is normal. I go to change the texturepack, thinking its faulty, but it happens in the default. When I change texturepacks, I can see the sun where it should be, but then it fades away in this virtual fog. It's not even white, it's gray. This does not happen in other worlds, just this specific world, with the preset Redstone Ready. Here's an image of the fog: http://imgur.com/jk6NZ
