"Escape to Salvation" - "Magnificent Retreat" [Campaign 4, Mission 4]

Got it! Thanks! There was just a small part that was hidden, and I didn't notice it. Now, all that's left is to take the central Castle! It gives 75 Cyclops, Angels, and Dragons. But that's still not enough. I should have pulled those 900 Cyclops to the surface and given them to Zephyr back in the day.
