So I was playing Advent on a medium-large map with three stars and four empires. I had already wiped out one empire, and was in the process of wiping out another when suddenly I got the defeat screen. "The unity's voice has gone silent!" I looked at the stats screen, and I definitely did not lose a cultural battle, as I had the highest culture. Honestly I don't play that often, so I don't know if there are certain special victories, but does anyone have a clue what happened?
