I did not change anything in the Vormur catacombs for now. Even though its def on my list of places that needs to be shaped up, I just gotta admit that for now it suffices and I spent most of the time on the new areas.
I should be able to get my hands on the map again before release, I need to do some more detailing at the new areas and perhaps If I get some spare time, I may look at the catacombs again.
