Playing as the Romans, they keep on calling themselves Hellenic.

examples:
- If you have the most armies, a message will come saying that 'Hellenic' armies are the strongest of the world
- If you lost a gate building in a siege, a message will come saying that it is an insult for 'Hellenic' courage
- If you kill an enemy general, it says you killed an enemy of the Hellenes
- If one of your cities is bribed, it says that the Gods are ashamed of such honourless Hellenes

etc. etc.

I guess it's a leftover from giving the Romans the Seleucid slot. There are also similar problems; like the Eastern Hellenic factions having Roman walls, and Rome having Greek walls etc.

Nothing game-breaking, though. Just thought I'd mention it.
