After updating and running the engine, i still had the same issues. I got Nemesis working, full mod list, loose animations, xpmse menu, NFF, sexlab framework, Flower Girls and CGO, with an information found here: I tried several combinations of all the above, and the problem only appears with CGO, and only for male characters using melee weapons. Worked perfectly with all of them, at least where being attacked by others is concerned. Then I uninstalled both and tried with Characters Behavior Enhanced, Nemesis PCEA and Ultimate Combat. Tried again with both XPMSE and CGO at the same time. I tried to change several CGO options, but nothing solved it. And no, it wasn't a generated file overwritten by other mods, I made sure the generated files are in the overwrite folder so they overwrite everything else, and the 'animationdatasinglefile.txt' file in the overwrite folder is the latest one.

And in 3rd person I could only roll in place. Male character only bashed, and could still perform killmoves, but no normal attacks. I noticed something strange: Only female characters attacked me with melee weapons. 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.
