I know that NPC's spawn randomly when you enter an area. I believe NPC's may be spawning in an awkward location and instantly dying. I noticed this by chance when I fast traveled to Hangman's Alley, I heard a death cry in the distance and I instantly got some experience points. I ran around the corner and I found a hostile caravan guard and no trader. I checked my Crime stats and I got a +1 murder stat. I checked a autosave prior to fast travel and I had 0 murders. (I am super sensitive about being good).

I am largely concerned about this glitch killing off roaming traders and other NPCs that I might have encountered.
