We are at war with a realm, and I noticed that nobles from that realm who do not have units are apparently able to travel unimpeded through my region. Is there anything I can do to prevent this or increase my odds of... catching them? I don't understand how it works.
It's fairly random. Odds increase if you use "patrol the streets", I think. Odds should also increase in more populated areas, and odds should increase when there are more soldiers in the region.
