I can not form raiding parties with my offspring. I can only find them when I transfer them to a place and make them governor. My two brothers and sister I can send out like any companion. I like to use this as a way to train them up to be good at governance. Is this just me? Also, I can not marry them off. In fact, I don't see many marriages taking place. Lots of single people, none getting married, my first character is about to die, and just about every strugian lord is about to die and leave no heir.
