Might want to reread that first paragraph. They renamed it from Evocar to Nal Hutta. Hutta is simply a short form or nickname for Nal Hutta. My point was that it is the same planet.
That's why I said it was not clear what the "renaming" meant just from the quote I posted. In any event, in this game, the planet is called 'Hutta."
But since the Evocii are still there, shouldn't it technically be called "Evocar," not "Nal Hutta" or even "Hutta?"
