Shadow Problems

[lazyshmuk]

I'm having trouble with shadows on my floor in a hallway. The room I built before it doesn't have this problem. They jump around with the camera and are at weird patterned angles. I have a box light that holds the whole room so i'm not sure why i have these shadows in the first place. They also show up on the Map Viewer when i'm looking at my map. How do I get them to go away?
