Ok. So i start playing as the Byzantines and go and seige Smyrna. On the last turn of the seige my faction heir and the entire army defects and becomes the new occupiers of Smyrna. Thought this was just a fluke so went to take revenge with another general. Last turn of seige He defects. Also while outside Moscow with a diplomat I saw the russian heir defect and take the whole defending army with him. And all this within the first 8 turns of my new byzantine campaign.
Have played them many times now and never seen it until now, my first time playing 1.3B
Have just seen a new open source thread but it doesnt mention anything about this?
Any ideas?
