Defence Strike Event Removed from Map

Bug Description: Defence Strike Event on your events diary and also seen by friend early morning, is no longer on Sydney Australia Maps. Are you now timing important events for 12 hours during night in Rest of World Regions or was this removed by mistake.

Area is was found in: Australia Maps

How do you reproduce the bug:

How often does it happen: First time strike event removed from Map before most ROW players can complete event. However now seen number of Incubator Events which the timing of does not suit Rest of the World players.
