My NPC's won't ragdoll

this happened shortly after i downloaded the decapitation mod
whenever i kill any npc’s, they won’t turn into retrievable, or pickupable ragdolls, and they don’t dismember properly. my body, when i die, does do this properly, but its recently stopped dismembering, and i’ve lost the blood spatter that usually comes out of the npc’s
what do i do?

Remove Dismemberment Mod.

where is it?

Where you put it. Check your addons folder. If it’s not there then re-download the file, read the read-me and check where it says you should have put it (if you put it there of course)
