So I have been searching all over for an answer to this problem and have only come up with a temporary fix. I was hoping that maybe somebody would see this and help me fix my game without restarting my current play through 50 hours in. Basically as the title says I can not loot Daughr, Vampires, Dragons, Daedra, Falmer and probably a few other I am forgetting. Not only that but I can't talk to any of these races for quests when needed meaning I can't talk to the dragon at the throat of the world and I can't talk to Serana for Dawnguard. I have how ever found a work around on another person's thread that bypasses the problem if you resurrect your character. This only works until you reload a save however and has other side effects like disabling my perks. It has also made my teleport mod not work unless I resurrect myself first. I have tried reloading old saves and starting a new game and the problem doesn't go away. I have removed all my mods and still no go... I have pretty much done everything I can think of but a re-install, and Id really rather not restart my game, especially if it doesn't fix the problem. Any help would be appreciated, thanks.
