That helps a lot.
You might check these Mod's descriptions and see if they conflict.
Fellout.esp
Nevada Skies.esp
Nevada Skies - URWLified.esp
Start by checking the Nevada Skies - URWLified description and install instructions.
As I remember you want the Navada Skies data assets and the Nevada Skies - URWLified.esp but not both.
I also thought I remembered they mention a possible issue with Fellout and Nevada Skies - URWLified.
Worse comes to worse use FOMM to disable a chunk of mods at a time (start with those three since they can be removed and added fairly simply) until you find the bug gone..
Then add them back in a couple at a time each night.
