this doesn’t explain why using the console command to force your wife to conceive, get the standard pop up message that she is with child but 2 years later she still hasn’t given birth.
when in an army character are no long are listed as travelling to, and instead it stays waiting at, but will no pregnancy. I tried to leave her in a city by starting a party and then disbanding it. Which caused to to stay at a city, however every time I waited at the city she would disappear from the keep and only reappear if I left and then returned.
Still I’ll give you’re method a try as I’ve tried everything else. I just figured that she spawned into my 1.5.1 game unable to have children and is unaffected by the changes in 1.5.2
