This mod adds a few pieces of scaffolding and construction materials into Frostmoth after the fort is damaged, and after the main quest is complete the fort will be repaired, requires Solstheim - Tomb of the Snow Prince.
For those playing Ashfall, this has the added benefit of restoring the well.
Edit of the vanilla version, Frostmoth Repaired, by Talthybius. If you use that version, make sure to clean the mod before use.

Any bugs or suggestions, let me know!
