Playing as Pontos. I noticed it appears to not be possible to build a local colony in Ephesus. At first I thought it was because it had a (medium) Polis and the manual was wrong, but it appears I can build it on any other settlement with anything smaller than a Metropolis. I have absolutely no idea what keeps me from building in Ephesus, even after consulting the files.
Code for Local (Eastern) Military Colony
Code/Proprieties of Ephesus
The only line of code that could be stopping it is the requirement "and not building_present_min_level hinterland_uniques3 threenine". That appears to be a large number of local unique "feature" buildings, and the only one that seems to apply to Ephesus is "{threenine_cul_1} Diagramma Hellenon Autonomias (Hellenic Autonomy)", that is also present in Helikarnassos, where I managed to build a Local Colony.
Finally... can someone tell me what is the name of the file for events/scripts?
