I'm only using The Underground 2, better bodies, and better heads. Along side Morrowind, and it's expansions.
Did you fully Update and Repair your save file with Wrye Mash?
The crash you're having is likely one of the common ones associated with that mod. You're crashing because of the 72 hour bug that the mod has, and since time passes when you fast-travel it happens then.
You have to open your Save file with TESAME or Enchanted Editor, and delete the two Cell references of Vladir's Crypt. I believe they are "Vladir's Crypt" and "West Gash, Vladir's Crypt."
That fixes the 72 hour crash that usually starts occurring during the part of the quest when you're going to Vos.
I have no clue how to run Wrye Mash.
