After we conquered the Forgotten Fortress we moved out of center until after the satellite crash. Then other people moved into center with no problem. As soon as I moved in to center my base was blown up. It said from the satellite drop but that was already over and no-one else got blown up. I have not gotten a new satellite code yet, does that matter?

there is a new rule. after you destroy the forgotten fortress, it attacks all those people who took part in destroying it.
it attacks every base within a range of 50 places.
So if you're near there, you will be destroyed.
i think it keeps destroying for about a week. so you have to stay away from the centre for a weeks time.
hope that helped.
