So I finally played a campaign long enough to have the mongols show up, and man, its weird. Completely bugged, though in an entertaining way. Basically, the mongols were ME hmy:. They show up and the 3 or 4 massive armies of like 20,000 mongols each were under my control, i got 5000 gold, and about 25 mongol characters entered my court . Hilarious, but obviously totally bugged. Any word on whether or not this has been fixed in the release patch?
