The EU3 Wiki says that the MTTH for the event $PROVINCENAME$ Revolts! is 50 months, but I'm literally getting this event every other day (Death and Taxes mod). I've only ever gone over the infamy limit once, and that was before Divine Wind came out. Now in my current game I thought it would be fun and challenging to conquer as much as possible (I'm already pretty large and have no other reason to continue playing), but the constant riots make the game unplayable, and there is no reason I can see why they should be occurring with such frequency.
