@ gadzooks-
I was unaware that Byzantennial merged. Especially considering that most members didn't go to Renaissance.
I never even got an invite. Thus, I am assuming that RedOmegaDeath and/or Paulzor decided to do away with that alliance. If you can prove that that milestone was given in error, I will revoke it.
Also, Poseidon Family did change their name (To Poseidon's Minions, I tihnk). I just left the old milestones as they were. So Byzantine Empire's milestons won't change to Domino Effect, for example.
Update: Folowing milestone acknowledged.
