Injury that destroys part does not wake sleeping mechanoid

[LWM]

If you shoot a mechanoid and completely destroy a body part, it does not wake the mechanoid.

Example: Jojo just shot the pikeman and shot off the rear right foot.  The mechanoid continues to sleep (its log is aware Jojo hit the pikeman with a bullet).

Expected: Jojo is murdered in so many ways by robotic horrors.

This also happens with melee weapons that completely destroy a part.

Thank you for the bug report.  How did you go about getting this bug to occur?  Do you use mods, and what version are you playing on?

In Unstable v1.2.2747 I have had a pawn cut off a part with melee and shoot off a part with ranged destroying the part completely, and it woke the mechs up on both accounts.

I got it to occur mostly be accident! I noticed it was happening a lot - my snipers would shoot off fingers from sleeping mechanoids when they dropped with psychic ship parts(etc).  I was not playing with Royalty.

I was probably playing modded. I don't think I play with anything that affects mechanoids or AI, but ....?

Maybe I should be playing with the Unstable build

In vanilla RimWorld, mechanoids do not have fingers, so I believe a mod is adding parts to a mechanoid that the mechanoid does not realize it has, therefore when they lose them they don't react.

I believe one actual example was a scyther's blade. I did not take any screenshots or notes, alas.

OK so I was wrong, apparently they do have thumbs, its just not listed as one of their hediffs.  However in unstable branch I shot off a scyther's thumb and they awoke.  I am going to assume this is fixed until otherwise reported again.
