Saw some mention of this in past beta posts, but I have a recurring bug that occurs after an invasion of one of my planets (might be double invasion of same planet, hard to tell).  After battle is loss, game hangs in invasion box and message "Waiting for other players" comes up and stays there...forever.  Only fix is to restore before the invasion, and then intercept the ships, but that is not always possible.  Game becomes totally hung, even after 15 minutes or more.  Any one got a work around?  GalCiv3 is busted until these little bugs are fixed.
