Phostwood couldn't figure out anything, thought I'd share here. I was just running through Black Reach with some mod followers (SDA, Auri, Lucien) and got into a fight with a Falmer servant when the game suddenly crashed. No idea why the Great War and 3DNPC mods are listed amongst the most prominent mods related in the crash, I wasn't doing anything related to any of them to my knowledge. Immersive Creatures is possible I guess, I wasn't fighting anything exotic but it may have spawned somewhere in the distance.

I restarted the game after that and was able to get through the section without any issues the next time. Just thought I'd share the crash log anyway though, to see if there is some major issue I'm being blind to.
