I got a problem with the daedra. They've stopped spawning their daedric weapons. Instead, they wield iron and steel weapons. This started happening within the past 2 hours. How come they're doing this? Is there a way to fix it?
Reason is, I want to have 2 daedric swords but unfortunately I don't know of any other way to get daedric weapons besides killing daedra.

I have Skyrim for Steam.
