Started a non-ironman game as Brandenburg. The year is currently 1515, I've become Prussia, I have a personal union with Bohemia and an alliance with Saxony. All three of us are electors and all three are Protestant, yet no Protestant League. I was the first nation in the world to become protestant, I even converted while Emperor, but no Leagues. I was under the impression that as soon as a single elector converted the leagues started. What gives?
