So I was doing the thieves guild quest line again, and happened to look something up on the wiki, and discovered that the NPCs in the Flagon should be talking to each other. The entire time I've played the game they never have. In fact the only time the the NPCs ever talk to each other is in the market in Whiterun. I've scoured the internet for other people having this problem, and could only find one instance. Is there any way to fix this?
