Yeah I'll confirm this. I encountered the same bug, and figured it was mods. I *sigh*'d and googled the issue to find an easier fix rather than process of elimination with my mods. After seeing OverlordQuasar's post, I determined that if his Locational Damage mod was the issue, then my DeadlyHeadshots was most likely mine. And it was. So, if you have the issue and happen to have one of these mods or something similar, it's probably the culprit.
