[1.2.2753] 24 damage to neck with sniper rifle

[Doomster]

In the savegame,

you can see corpses of Wolle and Barga, both having 24 damage to neck made with sniper rifle. That's weird because sniper rifle hits for 25 damage, like it did to Barga's left arm.

Does the game deliberately leave 1/25 neck health, so the head doesn't fall off? Nevertheless, it looks weird and buggy. When hunting a squirrel, you can end up with 0/10 of it's body left, damage shown as "Gunshot (sniper rifle): 25.0", and all the meat intact. Weird too but legit. You can do the same with neck, 0/25, and leave the head on.

Also, why do people perish if they still have 1/25 neck?

I'm not sure this is a bug.  Both pawns were wearing clothing, specifically a jacket and a parka.  Both grant some armor protection to the neck area which would have a chance of reducing damage.

I will report the neck at 1/25 though.
