If you've been following the discussion on the forums lately, you may have seen that a lot of it has involved the state of the various unofficial patches. We have started the Unofficial Morrowind Patch project with the intent of producing a single comprehensive patch for Morrowind.
We are going to use Thepal's UMP 1.6.3b as a base. We will fix any known issues with ThePal's UMP, then we will take the most popular unofficial patches and fixes and merge them into the base to create a new unified patch. This will be our first step. Once we've released a consolidated patch, we will work through the remaining list of outstanding bugs and start adding fixes for them to our new patch.
So, could you tell us which patches and fixes you are using?
