Playing as Macedon, I found out that Kallatis is not an Expansion region, but an Outlying region, although bordering my Homeland province of Odrysai. The nearby Getia and Getia Koile are Expansion regions, and even Skythia and the Western Crimea. Pantikapaion and Kolchis again are Outlying.

Well, I see it considerable that Pantikapaion and Kolchis are Outlying. But why Kallatis? And why is Skythia and the western Crimea Espansion Type?

I don't know if this is a bug, but it's strange anyway.
