I first encountered this when I tried to enter a certain mine dungeon near the Urshilaku Camp, Morrowind would repeatedly CTD. I didn't worry too much about it since I had no real reason to go inside, so I went about playing normally. Skip ahead to playing Tribunal content, and it has started happening again in certain areas of the sewers. First, I had the problem when trying to get into the cell with the Goblin Warchiefs. I disable all of my mods, leaving only Morrowind, Bloodmoon, and Tribunal, and still got CTDs. I finally decided to just use the 'journal' console command to skip ahead in the quest and used 'coc' to get past that area.

However, it's now occurring in several of the cells where I need to go to get to the Shrine of the Dead. I don't want to continue to have to use the console to maneuver around quests like this.

I tried making a brand new character on a brand new save to see if maybe my old save was corrupted, but I still got CTDs when trying to access those specific cells on the fresh save.

Does anyone know what could be causing this?

I had this problem when I first started playing morrowind. the game would always crash as soon as i enter Vivec, Foreign quarter. Then I didn't use MCP. It makes the game so much stable. If you are already using MCP, I don't know...

Yeah, I'm already using MCP. Thanks for the reply though.

Hmm... This usually indicates of some sort of a conflict, so I suggest that you post both your current loadorder (your loadorder when you got your first CTD) and the contents of Warnings.txt here.
