Yes, supposedly Aldabra.
There is some evidence that the 'move' was a genuine error, brought to the attention of the recipients of the paper which contained it by the Air Ministry (via the late Sir Michael Quinlan, who apparently never failed to be irritated by accusations that this was a deliberate ploy[he was in the Air Ministry at the time]) while other evidence suggests that even had the island been moved, the map/chart also showed the actual distances between the island and various locations, and the stated distances were correct.
There are other factors, but the idea that moving an island was a major reason that the CVA01 was cancelled is a complete and utter myth, even if there are plenty who fondly believe it.
