Does anyone know if the Mongols "invade" more than once. In my Russian campaign, the Mongols appeared with about 4 full stacks and one, I guess you'd call it a "retard stack". Anyway after I killed a few stacks and my military was the strongest in the world, I got a message telling me the Mongols were the strongest again. I sent some units to see what was going on, and the Mongols got more reinforcements. They currently do not have a settlement. Will they keep getting reinforcements until they settle, or is there something else? Great appreciation to anyone who can answer my question.
