hi, i'm getting that top left corner error message after killing any npc, not strictly humans but things like headcrabs and antlions. this happened as well with the usual fedhoria mod, i figured i might as well ask.
in short, i shoot the npc, they die -but they dont fall down or ragdoll like fedhoria usually does. fedhoria is enabled and so is keep corpses, only when i disable either of these do i not receive and error.

the error im getting is:

"[A fully edited fedhoria V8.4 Death facial animation and Death camera and Overkill]
lua/entities/active_ragdoll_controller.lua:119: Tried to use a NULL entity!
1. TranslateBoneToPhysBone - [C]:-1
2. unknown - lua/entities/active_ragdoll_controller.lua:119
3. Spawn - [C]:-1
4. StartModule - lua/fedhoria/modules.lua:35
5. unknown - lua/fedhoria.lua:186"

It must be some sort of conflicting mod? but i've sifted through all of my current mods and theres nothing that stands out as potentially causing an issue.
any help would be really appreciated, because im lost on how to fix this
