The Unofficial Morrowind Patch (UMP) fixes almost all of the bugs and problems with Morrowind and its expansions. While the official patches by Bethesda only fixed a couple of dozen bugs, this patch fixes several hundred.

I only just realised (in 2015) that this wasn't at the Nexus (since the Nexus didn't exist when Morrowind came out). This is the original Unofficial Morrowind Patch. It hasn't been updated for years, but this should make it easier to access for anyone wanting to use it still.
