I was playing along for several generations in the Duchy of Armenia Minor when due to no fault/skill of my own I suddenly wound up as King of Ruthenia. Obviously this dramatically changed my game experience. Yes Ruthenia is a wasteland of backwoods hillbillies but it does have manpower, if not technology. I eventually figured out that I needed to shift my capital to Tarsos to stop my horrible Demesne penalty but there is one other vexing issue. Heavy Horse! I had spent thousands developing Heavy Horse units in Tarsos, Adana, Teluch, Seleucia and sudenly they're gone.... just gone. No buildings, no Heavy horse and horse archers in the levies, no option to build the buildings necessary to produce them anywhere. Instead they were replaced with the option to build heavy infantry. Anyone have any ideas?
