The goal of the Unofficial Skyrim Patch (aka USKP) is to eventually fix every bug with Skyrim not officially resolved by the developers to the limits of the Creation Kit and community-developed tools, in one easy-to-install package.
Hundreds of gameplay, quest, NPC, object, item, text and placement bugs fixed. Created by the authors of the Unofficial Oblivion Patch series. No unsafe changes (such as deletions of stock objects). Designed to be compatible with as many other mods as possible.
