characters stopped killing (The Elder Scrolls 5: Skyrim)
the first was Logrolf. I completed the quest with the club through the console,then started the Rogue Conspiracy and ended up in the mine. So here the NPCs are also unkillable, tested on Madanakh, his guard and the Loser (whom Madanakh sends to kill), they just stand and do nothing, while the HP decreases, then the bar disappears and appears again on the next hit.

The console and also the assembly is not its own, why ask stupid questions when on the left assembly you also go through the game in these ways.
I also had it, and with a license, I installed a bunch of mods, and it just happened that the drogonborn dls came out, so my NPCs came to life, after finishing off with the head off, they got up abruptly and again into battle, and their damage went through invulnerability to me, even screened somehow, the headless were killing me, zombies their mother
Today I caught such a bug. It was necessary to kill some petty leader of the "Silver Hand". His health didn't drop at all. I decided to kill him through the console, but he did not die; just squatted down and you could finish him off without resistance. Quest completed.
