So I spent a while narrowing this down between mods, but generating a few dev quick test maps with a minimal mod list of all DLCs + Facial Animations + Altered Carbon causes errors with rendering as seen in the log.

These errors aren't restricted to pawns however, as I found in the log linked, seeing issues with a boomrat.

I tried generating around 50 dev quick test maps without this and it was fine with facial animations, but as soon as this is added it breaks again.

To be thorough, I ran the same without facial animations and observed other graphics-related errors:
