/>

antarctica - Impassable decoration, and also total Nation revamp (the
map had a low rotation of 1, it has been bumped to 4, it will not affect
players drastically since its a very rare map)
<img width="598" height="588" alt="Captura de pantalla 2026-07-22
170522"
src="https://github.com/user-attachments/assets/f0b764a7-129f-411f-a545-022007f05044"

caribbean - Impassable decoration
<img width="859" height="559" alt="Captura de pantalla 2026-07-22
170738"
src="https://github.com/user-attachments/assets/396527b5-b852-4263-af86-4597608c85df"
/>

japan - Impassable decoration (and also removes it from featured, it
honestly isnt that popular of a map to be there)
<img width="528" height="528" alt="Captura de pantalla 2026-07-22
172200"
src="https://github.com/user-attachments/assets/03241071-aee9-4e49-b6a3-c15029c12a34"
/>

milky way - Impassable decoration
<img width="581" height="573" alt="Captura de pantalla 2026-07-22
171957"
src="https://github.com/user-attachments/assets/54496b0d-1106-4296-8a89-bb5758c60420"
/>

korea - Boosted to 2 teams
taiwan - Boosted to 2 teams
caspiansea - Boosted to 2 teams
branching paths - Boosted to 3 teams instead of 2 (its a triangle, it
only makes sense)
