Strange one here. Everything in the game works fine until one of my opponents invade a planet. Then I can no longer invade his planets, I can't access any of the menus on the control panel, I can't even access the Main Menu to save the game. Seems like everything except the map functions and the turn button are locked out. I'm using version 1.11.029 and it appears this problem started as soon as I installed the udpate. Let me know if you need more info.
