Good day everyone.

First off please forgive me if this has been asked before, but I am new to this forum and haven't seen how to search for topics yet. Anyways...

I am relatively new to the Morrowind modding. I recently completed a playthrough and explored all of Vvardenfell and wanted to add TR to my that playthrough. But when I installed TR, all my map progress reset on Vvardenfell. The whole map was blank. I did a lot of scouring online, and all I find is that sometimes Morrowind's mainland won't load properly. Nothing specific to my reset issue. 

I understand that the recommendations are often to just starting a new play-through when adding large mods, and rightly so. But in hopes of continuing the playthrough for my original toon I thought I would ask: Is this just what happens when you play an old save with TR or is there a workaround I am missing?

Thanks in advance.
