As others have noted the events that should cause the mongols to crumble seems to have been coded to make it more unlikely after 1300 than before 1300.
I started a game in 1337 and was well into 1400 before I noticed this and altered the events. However I still can't get the dynastic succession event to trigger:
It seems as though it requires the liege to be over 35, but none of the mongol leaders in my game make it past 25 as they quickly get wounded in battle, become depressed and die young.
I am thinking of altering the age requirement, so I can get the event to trigger, however if I set it too low the liege won't have sired that many heirs. Where would be a good balance to set it so that the rulers will live long enough to trigger the event, but will also have had time to sire some heirs.
