Every child born is decreasing the chance for another child for parents. Are there any married NPC's that does not have any child?
The 7 young spouses/wives i mentioned before have no children at all. The oldest marriage i have out of the 7 is about 14 years. This wife is the oldest of the 7 at age 34. Only 2 wives out of the 7, are now in two year old marriages since i sat in the town for those two years. While sitting in the town for 2 years none of the 7 have gave birth. I used the "wait for some time" feature while doing this. So i guess you could say it has been 14 years since any one has had children.
Early game, i would get children quick. Weirdly i dont think i got less than 3. I'd change the wives and husbands all to virile perk (idk if spelled right.) At times some wives had up to 5 children. I have about 63 family members. My clan was a baby making machine. Then it just stopped happening completely. Wives with no children are not giving birth.
The only NPCs im seeing give birth now are just others clans in the feed.
I was making children as my routine to make sure each role i provided them with would always be filled. I usually didnt bother with trying to have children after the wife was 35, as i thought that was the cut off age.
I have sat at my town many times. Especially when i would smelt weapons, wait for more bandit hideouts to appear, or wait for some one to arrive to my party. So any of those times waiting should have triggered a baby. I am pretty positive it has came to a halt.
My only proof is that i sat in a town for 2 years straight and no babies from those 7 wives. Which i found odd. It caught my attention because my routine seemed to no longer work.
I figured maybe a recent update may have messed up my game or added a bug. But during my research, i found other gamers claiming that once they had 40 to 60 clan members, they noticed they were not getting births anymore (on a reddit thread). I assume they just started over, or just moved on as it has not been brought up in this forum.
I can provide names, ages, and how long the wives have been married that have no children if that helps anything.
