I am testing Mictlan in an SP game under 2.14. I have received that message twice now in the Last 10 turns. I am inclined to believe Kris about the sacrifice thing, for I am sacrificing so many slaves now that I am even pushing back an Ermor CPU 10 dominion. But I am also using the alchemist stone and trading fire gems for money, so that could have an effect too.
And no, I don't have to cheat to beat the CPUs!!!
