Ok...
Thanks for all your help !
Now I have a new thing quite interesting... I think it is a bug but I'm not sure :
If I take an Eastern Greek settelment, quite developped, I have some strange things with it.
I will take an example : Alexandropolis.
I took it last week, and there was the building "Satrapeia Seleukeia" in it. not strange, but this building (actualy a "governement building type II if I remember well) allow me to build all the partian reformed governement's building, including "Bûmdûr-î-Pahlavânig (Partian Colony) witch does not change anything if I build it. I am able to construct every reformed governement's building, including sewers, "strengh house" (if I remember well), big stone walls, paved road and other stuf like that. (all are partian culture...)
So I think it is a bug because it seems the "satrapeia Seleukeia" governement looks like it act as if it was partian governement.
If I destroy the eastern greek governement, all the possibilities of building disapear except the classical building like "military occupation" and "migration", "purification tent", "healer", etc...
I installed the 1.0 fix patches but I had that before the installation already so it does not come from it.
I think something goes wrong in the kingdom of Pahlavani
