Have you ever fitted Ada with a reaper head and watched her attack settlement settlers, only to find that some of them had their heads buried in the ground? The head is separated, but the NPC is still alive: this is "dismemberment before death".

There is currently no solution to address the root cause. Script-based patches are incomplete. They only override specific scripts, break compatibility, and leave out new mods. I (original author tryname, the same below) adopted an engine-level approach and hooked each disconnect call to the Havok endpoint (bhkWorld::SetDismemberedLimb).

feature

Hook bhkWorld::SetDismemberedLimb. The engine-level endpoint that every fragment call goes through, regardless of origin.

Two levels of flag checking (runtime boolFlags + base record) to correctly catch setessential and setprotected

Key NPC's names must be preserved, that's all. Protected NPC heads → will remain worn while alive and will only be removed when truly dead

14-byte absolute JMP hook - securely stackable with other F4SE plugins

Written in C++, it has almost no runtime overhead.

Install

Install using your mod manager. that's all.
