So I remember I had this problem before on a previous version on a previous playthrough back in 2019. I do not remember how I fixed it. What I do remember is that the draugr were, and still are the source of the problem.
Now what happens is that any time I get close to the shipwreck near the earth stone or go into a draugr barrow I CTD. I did try to use this; https://morroblivion.com/files/morroblivionobjectids.pdf to console a draugr to me, but none of the different codes for various draugr did anything.
Does anyone have any suggestions? I will admit, I am running with a lot of mods and I upgraded from the previous version, but does anyone have a draugr replacer I could try or a fix for this? Im fairly sure that the draugr are the source of the CTD issues.
I will aslo say that this version has been more buggy then my 2019 playthrough, with missing textures on silverware cups, some wood stairs in dungeons, the floor of the bars basement in Pelagiad and weird color changing candles (wax part not lighting). Also missing dialoge options for the gateway ghost quest and the one where the imperial merchant accidently stole an ashlander tribes hides. I also had CTD issues with the Tribunal quest where the plaza is under attack, but an old replacer for the fabricates (robo dino things) or whatever fixed that.

Do you use OCO2 mod?
Do you use OCO2 plugin?
