I think the problem might be a particle that I put in, but no matter how far back I go I cannot seem to get the lights to stop emanating from the ground! I have put a lot of hours on this level and would hate to start over. I am verifying integrity right now, but other than that I am not sure what to do!

Any help would be greatly appreciated.

EDIT: Restarting the game or verifying integrity works to fix this.
