Hi,
I've searched pretty far and wide, looking for a way to fix the purple Seyda Neen homes I've recently experienced. All I did, in order for this issue to arise, was disable Morroblivion + its related plugins. I decided to enable them again, start a new character, and enjoy Morroblivion, but now some houses (and a few other, minor meshes, like part of the wooden bridge) appear to be having texture issues. Just the walls, not the door or roof.
I've already re-downloaded Morroblivion in its entirety, and placed the mod back in my Oblivion directly (Data), but the issue is still there.
Just wondering if anyone knew of a way to fix it.

Try Re_install Shivering
Try Re_install Shivering Isles. If not a Number so we can Find Textures.
