Imperial Orcs

The Orcs conquered Averheim after I declined to help them defend the city, playing as Reikland. When I called a crusade on it to recover it I saw an Orcish stack led by a general and filled with Legio Averheim troops with peasant unit cards. Maybe someone forgot to disable recruitment of humans by orcs? They are also silver and untextured on the battlefield.
Just a bug for the next update to fix.
