One of the game servers has been offline for several hours. The game launches as normal without any errors but no orders are processed e.g. ordering a fleet to move or a building to construct has no effect. We’re looking into it now and will get it fixed as soon as possible. I’ll let you know as soon as I know more.
Update: the game servers should be back online. Please let us know if you continue to have any issues.
Apologies for any inconvenience and thanks for your understanding.
