Download Unofficial Dawnguard Patch

When the developers ignore bugs, the community does not. This is a patch for the Dawnguard DLC, fixing hundreds of bugs left over by Bethesda. Now that game-breaking bug won't prevent you from completing the quest. Note that this is the last version of the standalone patch. Current versions use the "Legendary" patch, which is available here on GameWatcher.
