No mongol invasion

I've been playing for 150 turns, no invasion showed up yet, i received the warning but no actual invasion actually took place. Im wondering is there a bug or something

The warning is between 128 and 144 years after the start of the game. The actual invasion is some ten to twenty turns after the warning. Maybe you will have to wait some turns. You will get a movie when the invasion happens. Good hunting. :sneaky:

There is also a warning when the horde crosses your borders and enters your domains.
