Not sure where to post this, but while in the Imperial City I just noticed that occasionally NPCs when having conversations will say something completely unrelated to what the NPC who initiated dialogue says. For example one NPC said "You got to love a store named Slash n Smash", while the other responded with "He supports all of your enchanted needs." Basically the response is to the wrong conversation sometimes. I noticed this when I spent a lot of time in the Imperial City without leaving. This also happened before in Skingrad, and I was spending a lot of time there as well.
