The ideal thing would be if someone made a compatibility patch for the two mods. This is why I stick to only using one of the beautification mods. For me personally the issues are too immersion breaking for me. However, my main point is that if you use FCO and NVR3 together you will have some strange issues popping up here and there. I know I am sounding like a broken record at this point, and most people don't agree with me.
