I'm late in a game, playing as Venice, and my empire is based on trade. I'm keeping my trade routes all coming out of Venice and I have as many as I can. Suddenly, 6 barbarian ships showed up in the waters right next to Venice. It was kind of like when you have a rebellion and barbarians appear, but my empire is extremely happy (80 happiness) and this was privateers and a galley instead of land units.
Does anyone know what's going on? Is all the trade bringing them in?
