Yes guys,I am playing EB with RTW 1.5. It seemed strange to me too to see a naval invasion in 1.5. I had a spy nearby so I could see what was happening, as I was going to take Massilia by see. In the early stages of the game a Hellanon Tiereme was approaching by coastline in southern Italy. In was carrying a small army, its destination is unknown as it was sunk by pirates.

Cheers.
