NPC defeat animation changes
This happened when they updated the Physx codex. Apparently the ragdoll effects are connected to that in some way.
It's a bug, not WAI.

We will honor the past, and fight to the last, it will be a good way to die...
I was cool with it myself, until I saw one of the guys I pummeled into defeat *twist into a bowtie at the waist*.
It was pretty sick. Cool, but sick, and wrong. Sickwrong. No. Wrongsick. Definitely.

This is houtex, aka Mike, signing off the forums. G'night all. - 10/26/2012
Well... perhaps I was premature about that whole 'signing off' thing... - 11-9-2012
I feel sorry for the rikti on the medical table in RWZ. Its twisted what they have done to that body.
I don't suffer from altitis, I enjoy every minute of it.
Thank you Devs & Community people for a great game.
So sad to be ending ):
Well, I like it better than the "bend over backwards and thrust out your junk" defeat post EVERY NPC seemed to have prior to this.

here you go..

I have to admit, this has been an amusing bug for me and my friend regarding sudden outbursts of 'THIS HOUSE IS UNCLEAN!' and 'YOUR MOTHER S*** C***** in H***', but I can definitely see the issue. XD

Having enemies' brains and blood squirting out their ears and nose, body parts and other gibs flying all over the place and sticking to things, and enemies screaming like babies in a fire when you nuke them would probably NOT be acceptable.

I don't know when the NPC Defeat animations changed (I only noticed in I21), but the new animations are disturbing. The defeated NPCs fold in half, the head spins, limbs rotate into impossible positions and sometimes the middle revolves so much that they look like hourglasses. I liked the old ragdoll style, but the spinning heads and folding are very off-putting.
