Kumarbi's historical cult centre, Urkesh, is in the east of Yamhad,
with Yamhad full of Ugaritic gods, this mod shift Kumarbi's discoverable location to Aber-Nahra (and also remains in Isuwa),
his in-game cult centre, Carchemish remains in Yamhad (close to Aber-Nahra boader).
i have tested that gods can be undiscoverable in their cult centre's region.
