About Oblivion's NPCs with Radiant AI going haywire and wrecking quests:
"In one Dark Brotherhood quest, you can meet up with this shady merchant who sells skooma. During testing, the NPC would be dead when the player got to him. Why? NPCs from the local skooma den were trying to get their fix, didnβt have any skooma, and were killing the merchant to get it!"
