Right now I'm the game master and we discuss the following scenario:
- Greece is empty
- all troops move at the same time
- Austrian fleet: Ionian Sea - Greece
- Osmanian fleet: Aegean Sea - Greece
- Italian fleet: East Mediterranean - Aegean Sea
So the result is that Greece stays empty but what happens to the Aegean Sea? In my opinion the Osmanian fleet gets defeated in Greece and comes back to the Aegean Sea but there is the Italian fleet waiting.
