I bought a home in Riften, and on this character, do not like the thought of a Thieves guild living under me.

What does my character do.. sneak down into the ratway to slaughter everything.. stealthily of course.

I get to the Main hall of the guild pecking away at members health.
Though I found something a miss, they weren't dieing, only kneeling down and getting back up...

I really don't have time to be looking into this myself, but I hope I'm not the only one a little annoyed at NPC's being un-killable, even by glass arrows at 3x stealth multiplier.
Can some modder, when the CK gets released,remove this problem?

I thought I read in the forums a long time ago that there would be no un-killable NPC's(children not included), I guess this is now false.
