Weird red triangles all over Old World Blues

[misanthrope]

I installed the game directly from the installer, without any mod managers. After getting to OWB, I was getting the sink crash, so I updated JIP LN NVSE. I still got the crash, so I installed NVAC. That fixed the problem. Now, when I go out, Big MT is filled with these red triangles. I assume they're some kind of error, is there something I can do to fix them?



Attached is also a screenshot of all mods I have.

The new JIPLN requires xNVSE (not the NVSE that's included with the TTW installer) and a newer (then the one TTW needed in the past) Microsoft Visual C++ Redistributable for it to work properly.
