Persia reborn (or something)

[Obelics]

for curiousity, is it possible to expand Kiat and Nisa to a more advanced settlement? For example in Nisa i cant built walls gardens etc. despite the fact i gave it Pastoralism...

My actual city i can build advanced things are Hecaromphilos, Asaak, Alexandria Ariana.

Again after i conquered Bactra i cant build advanced things. So is Batctra limited too?

Thanks!

I forgot: i have the same problem with Marakanda, i cant expand it.
