Giant X on my carpet

Shorah, I'm working on an age, and It's shaping up really good... however, in render, and Lightmapping, there's a big stupid X in the floor! I thought at first that it was the lighting. (I have a LOT of spot lights next to each other on each side, and one above) 
but... when I deleted all the spot lights, except for the overhead one, it STILL had the X, even with just one spot light, so it wasn't overlapping lights or anything. Anyone have ANY Idea what the heek is happening?
Here's a render (and the X
):
