The one thing I never noticed was that the dish bisected the equatorial trench in the plans. I wonder if that is something Ady will fix for his new Star Wars Revisited project.
He did that almost 10 years ago now:
But he is changing it back thanks to Rogue One, I believe with the argument the Story Group came up with that the plans contain all of the variations and each one had the exhaust port.
Looks like the original design was actually built. Kind of too close to home for me though 😃
