In my youngest city, I just noticed a small amount of Orc Warriors in my army camp. Less than a squad. But there should not be any. That city is currently in the early stages of the Orcs chapter, but has not unlocked Orc Warriors in the tech tree. And there is not a single building in the city which is capable of making Orc Warriors. So I am a bit puzzled where they might have come from. Anybody have any ideas?
