The outer portals are fine (the ones you and 709 fixed). The boogered up stuff is around the main ring (with the fancy numbers) at spawn. I came back in from the Outlands (I'm gonna call it that) and dropped through the endstone down onto the main island. Fortunately, there was ground below me. However, if you run around that clock-compass-ring, some of the portals are sitting over empty space, so if the problem happens there, you die!
