"Disintegrated Textures"

[amd64gamer]

Ran across this bizarre visual glitch while playing Fallout NV:

This is inside the building where Ranger Chief Hanlon is at Camp Golf.
I don't have a lot of mods installed but I do have some texture replacers.
Everything is patched up to the latest, load order sorted with BOSS and I
also have a bashed patch.

I was inside Repconn HQ and I noticed a similar effect with the stands that the
items in the museum were sitting on (the textures looked as if something
"disintegrated" them. I uninstalled the POCO BUENO Texture Pack and installed
NMCs Texture Pack (medium resolution).

After turning archive invalidation off then on through Nexus Mod Manger and
reloading the game, the missing/partially "disintegrated" museum stands were
displaying normally again. But the walls inside the Camp Golf building were
still messed up.

I had a similar problem with Protectron Police Robots inside the chambers in
the DC Metro System in Fallout 3--it was like part of their textures had been
erased with a jagged eraser. Inside the Museum in the Washington Mall where you
retrieve the satellite dish for Tree Dog was worse than the interior at Camp Golf.

I'm wondering if these issues are linked to some kind of conflict with textures,
or if there are specific ones causing a problem. I know Bethesda reuses a lot of
interior textures in the game, and Camp Golf is the only place I've run into this
so far.
