I'm in the process of making a mod that fuses the Balkans with the Eastern front. However, one of the things I noticed is that the Mediterranean Sea (and its sections like the Adriatic, Aegean etc), seem to be off limits. Amphibious forces can't seem to be able to cross it and I'm not sure if supply actually flow from one port to another.

Is there a way to open these seas or make them into a sea zone?
