Of course, I had forgotten about the fact that when you use landscape retextures, elevations are often altered, and thus conflicts occur with many buildings that rest on hills.
I just installed Balmora Expanded, and discovered that most of the upper districts are covered by rock...
Now, considering the main storyline of the game.. I can easily imagine this to be the consequence of a severe seismic disturbance and simply enjoy the areas of BE that are available, this isn't a problem, and I'm not unduly fussed.
However, I am curious... has anyone ever discovered a work around for this issue? I mean, BE is a popular mod, and most people these days like to use graphic enhancements, so I'd be a bit surprised if this were not the case. I looked around Google, though, and didn't really find anything.
BTW, before anyone asks, I am already using the land texture fix designed for BE by Slartibartfast .
