Here are couple of pics:
This is what I see in CK.. the edge is nice and smooth, looks natural

And this is what I see in game.. The same edge looks like it's been cut off...

I created a brand new esp file and attempted to put the same house in the same spot without setting it to Full LOD. Upon one fast travel and back, the house was invisible. In the original mod I'm working on however, no matter what character I use or what save file I use and how much I fast travel, I can't duplicate this bug anymore. I don't want to raise my hopes up and get too happy.. but if something made it go away I wish I knew what it was so I could tell others.
