I had this same thing happen in a early version of my mod Merc 2, but it was much more extreme with how much stuff was around the Player. So much that the Player died as soon as entering the Cell. I will look back and see if I can remember how I fixed it, but it might be a few days. Odd thing was it was a Cell that I really did nothing too in the GECK. The Player just had to pass through on the way to a Quest. It was only when the Player entered into Friendship Station in the tunnels. What makes you think you did something to make it happen?
