NPCs such as guards don't react to hostile NPCs

I installed the latest version of US through Automaton and added a bunch of extra mods, but now I'm running into some AI bugs. At the start of my game, I had aggroed some bandits and let them toward the giants' camp near Whiterun who then wiped them out...As I got closer to Whiterun hold, a bunch of other bandits showed up and attacked me, but none of the Whiterun NPCs attacked back. I led the bandits right up to the guards, Aela, Urthgerd, etc...but all the friendly NPCs just ran back and forth. My mod list here: https://modwat.ch/u/RinWes/plugins

Does anything in my list stick out to you as an obvious issue? Thanks for any feedback.
