I've noticed this ever since the game came out that in the world of skyrim only half of the worlds light sources create shadows on characters and objects, when they do it's dynamic and i can appreciate the dungeons and interiors more, gives the world a homier and dynamic feel. But it bothers me when I walk into dragons reach and the massive bright fire in the courtroom fails to create shadows on anything. For me this takes my train of thought away from the quest and game and now onto this distraction that ruins the feel. That and I've noticed some weird occurances with sword and shield noises sounding terrible then good again. And finally what ever happened to footprints in snow and flow based water?

Odds are Bethesda won't release a patch anytime soon. Perhaps 1.9 was the final patch.

As to your footprints question, all that was part of their game jam video. Some of the content in that video made it into the DLC, and some if it didnt.
