Immersive Civil War Cleanup
The Skyrim Civil War is a huge part of the game. Without getting too much into it, you'll side with the Stormcloaks or the Empire (Imperials) during the game and go on a pretty extensive quest line.
Once you get through the quest line, some of the cities/towns in the game will look damaged. It's immersive yes but at some point you'd think the citizens (and the government) of these places would do some cleanup after the destruction.
If you don't like the look of the debris this mod will rebuild the buildings that were damaged during the civil war quest line.
Immersive Civil War Cleanup is a tiny mod (16MB) for Xbox One that allows you to patch up these buildings by talking Ulfric or General Tullius at any time after the conclusion of the quest line.
