Playing a Conquest game and lost (Do not start at Tech Level 0). My only shipyard was taken, then my last remaining airship destroyed, and the game did not register the game was over and kept playing. I thought I could claw it back by finishing the cultist tech tree before all my towns were taken and I lost my money, but it turns out you can't summon the Kraken except at a shipyard so there wasn't a way for me to make more units.
