Problem with tradeports?

[Hildico]

As Koinon Hellenon I can't expand the tradeports of Athens and Rhodes. Is this meant to be the case or is this a bug?

Having spooted this, out of curiosity, I started a Roman campaign and destroyed the higher level tradeports at Rome and Capua then rebuilt the bottom level port in both provinces. When completed I found that I could expand the port in Capua but not in Rome. Can someone tell me why this should be the case?

Thanks in advance

I'll be making maps for where you can put tradeports and higher level ones soon. I'll definitely post it for everyone when I get it done. Some places just can't have as good sea trade as others is the bottom line.

What confused me is that Rome starts with the largest tradeport but if I destroy this building and then rebuild the smallest tradeport it cannot then be expanded

We haven't dealt with ports in a while and all of them are being looked over currently. They are in need of a good overhaul.
