@677714f16587604b Definitely have a look at your Neighbourhood Stories settings at a per-household level in Manage Households, and check any mods you have (like MC Command Center) that might do anything with households too.
I've checked all saves. The 100 babies does not show up in Loads. :-(
Well, if I load the spellcasters, I can go to the Managed worlds, find the 100 babies household and play the household though there is no point really, the matriarch is old and will soon die, daughters live elsewhere and are old as well or dead. As I have said, I can't load 100 babies household from Load games because it's not there. Funny thing, before starting the spellcaster game, I had been playing 100 babies household for a while. I could either "resume" or "load game", no problems. At which point after starting the spellcasters the 100 babies disappeared, I can't be sure.
@677714f16587604bYour spellcasters and your 100 baby challenge are in the same save. The matriarch is old because time passed while you were playing the spellcasters and she aged up. That's why Luth suggested using the recovery feature to roll back to an earlier version of the save.
First, if you want to keep your spellcasters, open the save and do a "save as" then return to the main menu.
In the load menu, you should now have 2 copies of the spellcasters; the new one that you'll be keeping to play with them, and the old one that we're going to roll back in hopes of recovering your 100 baby challenge.
In the load menu, click on the original save that has your spellcasters & 100 baby challenge, so that it's highlighted. You'll now have a recover save option.
Click recover save, and it will pop up a menu of previous saves, dated to when each occurred. If you can go back to when you first switched to the spellcasters, go ahead and do so - or just go as far back as possible. See if the matriarch hasn't aged up yet.
Good luck!
