Fixing unresponsive unwind segues in iOS 8

This fixed a couple of unwind segue's for me, but not for all of them. I have an app with the centre view as a navigation controller. Some views get pushed onto the nav stack, with one being a view controller with an embedded page view controller. One of the view controllers in the page view controller is then modally showing a scene, which is itself in a navigation controller. The unwind segue to go back from there does not work. However, I have another modal scene (in a navigation controller) begin shown from this view, and it's unwind segue does work.

Any thoughts on that?
