Should there be a Hellenistic Polis building in Syrakousai?

[QuintusSertorius]

I'll readily admit that while I like the new culture development mechanics, I don't really understand them at all. Even after reading the building browser. I feel like some of the requirements are missing or there's too much cross-referencing/nested requirements for me to grasp what's needed.

Either way, Syrakousai has no Hellenistic Poleis building in it. In spite of being Greek and having 70% Hellenistic Polities already. Other Greek-founded settlements I've taken (like Massalia and Emporion) have small Poleis buildings, which will no doubt eventually be upgrade-able. But Syrakousai has none.

Is that an error?
