I'm not sure how many people noticed, but whenever you interact with objects on a table or other surface, they all instantly float a few inches above the surface... kinda immersion breaking and annoying...

Does anyone know if this has been fixed in Skyrim?

There's 1000000 more important things to worry about.

I'd like a full list of them

But it sure is an important thing to worry about, I don't recall any in Fo3 though and my hopes are high that they have been totally removed in Skyrim.
