Roof of the building right above the entryway is missing Roadway LOD. At least on the thingies. I don't know the word for them, in German it's "Zinnen". You can see them on the screenshot
Also below the Center Tower You can see through the floor of the highest floor
The destroyed variant of the Tower is also missing Roadway LOD higher up. At the first "destroyed level" there is still a patch of walkable surface at the top but it doesn't have a roadway.
Directly on the right of the players head on the screenshot.
Same Tower. Same damage level a texture bug when looking up from below
