Vanishing Calaware

[nairagorn]

Been playing as Casse, I made two units of Calawre, but the option to build them has dissapeared! Is there a limit to how many you can have active? I haven't torn down any buildings in the city where they were created, I don't understand why the ability to make them would just vanish. Can't retrain them either.

You probably built a gov't building.
