Whenver I'm walking around Falkreath exterior, the game crashes to desktop. I'm using a lot of mods, but that's the only location where I get CTD during this 40 hour long playthrough.

My load order is below. One of those mods is causing the issue, I'm not sure which one.

Why you don't disable those !!! (each time 10 mods), and load that save near Falkreath.
