Have they fixed the Khergit ranged troops actually being marked as cavalry? I know it sounds weird, but the cavalry flag which is assigned to them prevents the troops from holding their assigned position in sieges, and makes them move towards the defence point. Without archers holding to their spawn points, their castles are considerably weaker. I have manually fixed that by changing the "cavalry" flag to "archers" for the units which have bows. Through that, the Khergits can act in a normal way while defending their castles/towns. An official fix would be welcome on that regard.
