I've recently started an Epeiros game (version 2.35) and I can't seem to recruit any standard phalangites. Deuteroi, agema, and mercenary phalangites are available, but regular old phalangitai don't show up anywhere. I've checked the building browsers in Epirus, Thessaly, and various other Greek provinces I control and none of the government or colony buildings offer them. They show up correctly in the recruitment viewer, but apparently not in the game. I have yet to see this problem with any other Hellenistic faction.
Any advice is appreciated!
