Second Rebellion happened. Dictator for Life dies from volcano erupting in Cannae. The successor has no trait that says Caesar Imperator, or Dictator for Life. He's simply the faction leader and is called proconsul. What happened?
EDIT: Does it have something to do with the family switching in the process? The Dictator for Life was from the Maximus tree, and the new national leader is from the Nepos tree.
EDIT EDIT: Nope. It doesn't work in the same family tree either.
