Does anyone know if it's actually possible for an AI controlled faction to beat the player in BI by achieving its victory conditions? I just saw a screenshot of a friend's ERE campaign where the Franks (victory conditions: 20 provinces including 3 in Gaul) owned 21 provinces, including the whole of Gaul by any stretch of the imagination. Yet they weren't awarded victory and my friend went on to win the campaign.

Has anyone ever been beaten by the AI without being eliminated, or received a message warning that an AI faction is about to win?
