I've done a quick check of their patch notes and didn't see anything that stood out. They played a bit with the Livonian Order so it may have broken something with that specific society. I'll need to check.
@Ursanclaw
As the other Ursus said, it is a semi-random world wide event. You cannot really force it outside of winning missions and some other small factors that influence the influence. This is why there is 3 "options" at that step, I've put all of the more annoying/limited things together.
@myrt
I assume you used the console or some clever exploits to force yourself to be the Grand Master of a real Holy Order? None of the events involving my holy order societies were designed to include the Grand Master as a human player, as Paradox did not make these legitimately playable, and this is why the rank 4 of the societies have no powers/special decisions. So the localization, titles and some of the society's events might break.
I do not really plan on fixing that unless Paradox legitimize them. That would be like telling Paradox that playing as the Papacy cause bugs.
But I'll fix that typo, my "Holy Fury Update" has not gone through a spellchecker yet.
You seem to be using HIP, I haven't checked yet, but did you see anything out of the ordinary beside what you have reported?
