I was reading through some other threads dealing with this same problem and I found this post:

MoreKids1_desc
MoreKids1_effects_desc
to your "export_descr_VnVs_enums.txt"
and this:
Code:
¬--------------------
{MoreKids1}
No Text
{MoreKids1_desc}
Extra Fertility
{MoreKids1_effects_desc}
No Text
to the "export_VnVs.txt" in the 'text' folder
This gives all family members extra fertility as a hidden stat. However, there seems to be a hard-coded max limit to the number of family members you can have and there's nothing modders can do about that. This little mod makes sure your family will have kids a bit faster if there's still room left in the family tree.
I can turn this into a sub-mod, but I have already made a lot of other changes to my files, which not everyone will like.
I added this to the files in my game and I have some questions about this.
1.) in this code:
Code:
Trait MoreKids
Characters family
Hidden
Level MoreKids1
Description MoreKids1_desc
EffectsDescription MoreKids1_effects_desc
Threshold 1
Effect Fertility 2
Should I leave the Fertility at 2 for the best results or should I change it to 10?
2.) Since I added this, at about 80 or so turns, the game started crashing. Is it probably from adding the above codes?
I asked ZaPPPa about this originally, but he hasn't been on since 10:00 am this morning.
