This is quite hard to explain, I have a problem with 2 exterior world spaces, in both cases - when I first enter the area everything is fine (Cell 00,00). I can see looking into the distance that everything is where it should be, and is how it has been placed. As soon as I walk out of cell 00,00 into the next cell I end up on a square of terrain about 200 meters above the cell, every cell except 00,00 appears to have it's own square at a different height. if I walk into a different cell I appear on it's square, way up in the sky. If I walk back into 00,00 I fall off the side and after about 5 seconds of falling hit the floor, and obviously don't survive. Any ideas what I'm missing or how I fix this? Thank you.
