Don't know much about Romny. Is it a former country or was at one point independent? If so, I'd say it's worth keeping. We have Shilage, Voslage, and the Republic of Anea in that category after all.
In the case of Shilage and Voslage they are correctly identified as "historic nations" on Usea (before they became part of Erusea).
On Verusa independent nations are Verusa, Sotoa, Kaluga and Yuktobania, but Romny is one of the "Yuktobanian Republics" and once you click on "Yuktobania Politics" Romny shows up as the only known member state / republic we currently know of.
Alternatively, it could read "Yuktobania including the Republic of Romny" but Romny is not an independent single nation like the other three.
Since this has been resolved by this edit, I'm locking this thread.
