So I'm running a lightly modded New Vegas and everything seems to be running great. However, occasionally after entering/existing an interior space all the shrubs/bushes turn into black triangles:

I'd think it's a texture issue, but they work fine most the time. I've also had the interior of a building lose all it's floor textures and just turn back. To fix this I restart the game and it's fine again. What on earth can be causing that?

Here's my mod list, sorted by BOSS:

Just to rule out the obvious, have you applied archive invalidation to your mods that add textures and models?
