There are two contradictory stories detailing the evacuation of Yavin IV, so what's the solution? The Alliance cleared out, waited for the Empire to finish searching the area, and then CAME BACK TO YAVIN IV. WITHIN SIX MONTHS. There's also two accounts of Luke's first meeting with Boba Fett. The solution? When Luke met Boba in the Holiday Special, the colors of his suit are different enough so that he DOESN'T RECOGNIZE HIM THE SECOND TIME AROUND. Congrats, Luke. You're a moron. And again, this is within SIX MONTHS.
I'll take the Clone Wars (which is certainly not free of its own continuity blunders, thanks mostly to that damned cartoon) any day.
