Mac: Special Missions - not showing in menu

I’m on the sixth initiation, and no special mission is appearing on the location.
I have 74 faction rating, and have even done more to raise that further, but can’t until I do this mission.
But the mission never shows up.

how can I rectify this?

I’ve encountered this once on my many campaigns (PC). It never showed up. I also think other factions never matured in that play through. I as l was forced to take the PP ending.
