Tes5Mod:Unofficial Skyrim Patch

The Unofficial Skyrim Special Edition Patch (USSEP) is a major mod started by Quarn and Kivan, and currently coordinated by Arthmoor, that fixes numerous bugs left over even after the latest official patch is applied to Skyrim. These fixes range in importance from dialogue typos to quest-breaking bugs to reducing save file bloat, and cover both the vanilla game and the official Dawnguard, Hearthfire, and Dragonborn add-ons.

The USSEP is incompatible with the Legendary Edition of the game; the older Unofficial Skyrim Legendary Edition Patch (USLEEP or USLEP) mod should be used for that edition. Likewise the USLEEP mod is incompatible with the Special Edition of the game. See where to download for links.

The Unofficial Patch was originally packaged in a series of discrete mods specific to the aforementioned game components and designed to work in concert: Unofficial Skyrim Patch, Unofficial Dawnguard Patch, and Unofficial Dragonborn Patch. After the release of the Legendary Edition of the game which included all three add-ons, these separate mods were discontinued in favor of the unified USLEEP mod which required all three of the aforementioned add-ons and was first formally released on November 7, 2015. Unification made upkeep significantly easier and enabled several fixes to be implemented that could not be done with discrete patches.  Though the stand-alone patches are now essentially obsolete (and have been removed from most download sites), they can be used in a case of running just the original base game, or the base game plus one DLC but not the other.

An Unofficial High Resolution Patch exists, which fixes bugs for the official High Resolution add-on. and is designed to work alongside USLEEP.

With the release of Skyrim Special Edition, the patches diverged into the USLEEP and the USSEP, with the first release under the USSEP acronym on October 28, 2016. The USSEP incorporated the Unofficial High Resolution Patch making that patch defunct for the Special Edition.

The major fixes are being gradually added to UESP. Should you want to help point out such a fix, please use the   template to do so. Specifically, you should use  . Optionally, you can also add a fourth parameter to give more information on any notable details about the fix. For other variations or special cases, see the template's documentation.

Note that this patch is unofficial.  The official (Bethesda-released) patches are documented at Patch and Special Edition Patch; the official patches include some fixes that for technical reasons (e.g., altering the game's executable) cannot be incorporated into the unofficial patches.  Therefore, installing the official patches is still required.  Also, the unofficial patch is not available for Xbox 360 and PS3 players, as they cannot install any third-party content.
