Uninstalled XPMSE, installed CGO, ran Nemesis and with the Companions again. Then I installed XPMSE, ran Nemesis again, and then tried the same thing, starting a new game and starting at Jorrvaskr. Started at the Companions using AS, punched someone and everyone attacked me normally, as expected since no animations were installed.

I ran Nemesis, but since I have no other animations installed it counted 0 animations. I cleaned my overwrite folder and then I installed SKSE, Alternate Start, SkyUI and Nemesis. Starting with a new MO2 profile with no mods, and no manually installed mods outside of MO2, making 100% sure nothing remains of previous installed mods. While last time I tried I had this problem without CGO, this time it seems to be the culprit I've been away for a while but now I'm back to playing Skyrim and I decided to test a bit for this issue now that Nemesis was updated.
