I'm losing my eldest daughter, I have to have her as part of my army so I allocated her to the Archers "II" but I never see her there. At the end of the battle, she's always injured. I think she's actually part of the Cavalry "III" or Infantry "I" ??? She's on a horse so she should be easy to spot .. but .. I hope she isn't being secretly allocated to "Skirmishers" "V" or higher, as they are placed in weird places (next to enemy)
Yes, there is a mod to fix none saving of Group Details.
