Turmoil and Unrest

No I was saying that may be a reason.


Ulm has spies, Spies can "Instill Unrest" and have (I believe) Stealth (+30), so they are hard to find without 20+ human patrollers.

Is the Ulm player playing Black Forest? It may be some Black Forest thing that I never noticed.

I'd have to check all the themes for Jotun but I don't believe they get a spy that can instill unrest.

You might want to look at stealthy units carrying around magic items. I don't know of any that cause unrest, but you never know. And if Jotun is in the game, maybe some demons. Send out a big pile of patrollers in those unrest provinces and see if you can catch anyone/thing.
