All of a sudden every single one of my rulers became imposters. I'm playing Epeiros and its around 250 BC and all my governments were Type 1 and 2. Is there a way to fix this? I have a save game from a few turns before it happens but I'm afraid it will just happen again. Seems like most or the stuff I'ver found regarding imposter bugs is regarding type 4 governments. Any information would be greatly appreciated.
