In my current game my vassals stopped being counted as "relations" in the diplomacy screen at some point. They're still my vassals but they don't add to the number of relations (unless I have another relation, like a royal marriage, with them). Is this a bug or is due to technology or HRE reforms (I'm the emperor)? I have all the reform except for the last two.
Speaking of HRE reforms, there's one that gives "+25% to imperial authority" according to the tooltip but I'm not seeing any change regarding authority after I've enacted it.
