We just won a 2v2 game vs AI with a Wonder Victory, but my wonder had been destroyed, and no one else built a wonder. It’s as though the timer kept going, although I don’t recall seeing a timer or objective after my wonder was destroyed and the end screen doesn’t show defending the wonder as an objective. So suddenly, while just playing, the game ended and said we won due to a wonder. The post-game screens confirm it.
I think my wonder lasted around 7 minutes before the AI came in and destroyed it. As we pushed into the enemy base, we got the wonder victory condition.
