Trigger for mutiny at Craster's keep

[Maslmasch]

Hi,

I am playing this fabulous mod (v.4.1) and was wondering what the trigger was for this quest? I am currently at day 354 and Jeor is still alive and kicking. In my last playthrough in the version before I can't remember it taking so long for him to kick the bucket... I already finished the "The Lands of Always Winter" Quests.
