I believe this bug started after the Diplomatic Immunity quest though I can't be sure, soon after in any case. Basically the Thalmor are friendly, no matter what. Doesn't matter what quest I'm doing or anything. I can run into a group of them, punch one of them to death, he will never fight back, and none of the others will react either. It's only the Thalmor, no other faction is showing this problem and it's one of one save file, different save files don't have this problem. I also have over a hundred mods installed and if I google the problem I can't find anything like it. Obviously this make large portions of the game very boring but I don't know where to start fixing it. Has anyone ever heard of anything like this?
Below is a list of every mod I have installed that I could possibly imagine affecting this issue.
