Everytime my character performs a finishing move (killmove) it seems my one-handed sword behaves like a dagger: the weapon grip is changed to backhand, and instead of impaling the enemy actor as would normally happen, he is stabbed. So the animations, it seems, belong to the dagger killmoves. Anybody else experiencing the same bug? Is there any known way to fix this?

I have no animation-related mods, so I don't think its mod related. But I could be wrong.

It's been like this for long and it's not mod related.

Thanks a lot. I assume you don't know any fix, perhaps one made by an external party? I can't seem to find one.

No I don't. I just keep it that way.
