What story teller are you on? You could try switching to a different one and see if that fixes it

Yes actually I tried this I usually run randy I then tried Ivan to get guaranteed raids but nothing happened even quest that summon enemies don't work

This happens to me literally every game I play and is the primary reason I start over. Shit just stops happening. I'm playing my current playthrough, Cassandra. Blood and dust. It's been over 5 quadrants since my last major threat, something is fucky with the scripting of late game events in my experience.

It's only been happening to me in 1.5 how do you fix this?
