Tes4Mod:Unofficial Oblivion Patch
The Unofficial Oblivion Patch, Unofficial Shivering Isles Patch and Unofficial Official Mods Patch are major mods by Quarn and Kivan that fix over 1,800 bugs (and 70,000 object placement errors) left over even after the latest official patch is applied. These fixes range in importance from trees that seem to float in the air up to conflicts that could cause the game to crash.
Note that these patches are all unofficial. The official (Bethesda-released) patches are documented at 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 recommended, in particular for fixing the Reference Bug problem. Also, the unofficial patches are only available to PC players; Xbox 360 and PS3 players cannot install any third-party content.
