Hello

I have big problem with dark brotherhood. I wanted to join them so I enter DB lair and textures disappear in 1-2 after enter.
The only thing i could see is me falling down and hear voice of Astrid telling me something about DB.

Anyone know how to fix it ?

Ps. I dont have any mods connected with Dark Brotherhood or Dungeons (only had realistic light but uninstalled it already)

it isnt textures, its meshes.
If its texture, you cant see anything but u wont fall.

As far as i know, i am getting them too. You are using 1.5.26 right? Do you have any mods that changes textures/meshes(e.g. water,skyrim 2k HD etc). Disable those and make a clean save and see. If its still there, i dont know. But i do know that 1.5.26 is a bad patch.
It supposes to 'fix' CTD, crashes but after updating, i get more ctd, bloated saves, vampirism bugged, this and that, random freezes even though i disabled all mods and started a vanilla char.

Thanks! It worked, i disabled every mod connected with stuff you mention and now everything is ok
