Slitherine

When playing the new mission "find Thorands aerie" I´ve experienced that the AI (purple enemy )invasion doesn´t trigger.

I´m playing on the highest difficulty with Iron Maiden and enemy scaling, and I think that the unit (yellow) I need to find to trigger it have actually been killed by the AI before I found it. When I first found yellow air units, there were only two.

Any fix for this, or do I have to start the entire campaign over?

That should be fixed with our last patch. Do you still have the issue?

I haven´t experienced it more than the one time.
