2) There is no explanation of how Obi figures out to go to Kamino. None. He takes the dart to the analysis droids, they tell him pretty much nothing, and suddenly he's in the library trying to find Kamino (which of course he names without any previous reference to it).

From the edit detail page:

- "Kamino" (in Aurabesh type) is now seen flashing on the computer display during the Jedi temple analysis scene. We also hear a results tone before the reveal.

I see. We are required to know how to read Aurabesh in order to follow a major plot point. And the "results tone" is supposedly meant to clue us in.

This seems like something Lucas would have changed.
