Requires Skyrim version or higher.


A comprehensive bugfixing mod for The Elder Scrolls V: Skyrim, 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.

For more information (ie the recent changelog, mods that the USKP replaces) see the USKP's threads on the AFK Mods forum here.

The complete changelog is posted here.

If you're experiencing a bug with Skyrim, please report the bug to us in as much detail as possible on the USKP bugtracker. Please use search to ensure that you aren't submitting something that is already there.

After installing the individual mods, the following general load order needs to be followed:

For getting load order set with other mods loaded, please use LOOT. It will provide you a solid starting point for everything that you can then tweak as needed.

Errors During NMM Installation

If you get the following error:

BOSS_API_ERROR_INVALID_ARGS: Master files must load before other plugins. The mod was not installed.

You need to perform the following steps:

- Uninstall and delete all the Unofficial patches in NMM.
- Exit NMM.
- Launch NMM again.
- Download and install all of the updated Unofficial Patches.
- Run LOOT to sort your load order.

Cannot Absorb Dragon Souls

Make sure your load order is right!

[Other ESMs]
Official hi-res DLC
[Other ESPs]

Use LOOT - you'll enjoy life more.

Loose Scripts in DataScripts

Check for: dragonactorscript.pex and/or mqkilldragonscript.pex. Remove them if present. They are from dragon mods that came as loose files.

DSAMG - Dragon Soul Absorb More Glorious, and Diversified Dragons are known to cause this. Those mods need to be updated with a Dragonborn patch that incorporates the fixes from the UDBP.

Others may be a factor as well.

Note too that the offending mod may have the script packaged inside a BSA. That will need to be handled by that mod's author.
