Sim cancels her labor, no baby

I got an idea and tried doing a science baby and she goes away and the music plays and then resets and no baby.

Update!  When the daughter of my Sim grew up, she was able to successfully birth a child.  So whatever the issue is, it's just the one SIM.

Hi squeaktastic​ 

is there anything special about the Sim ? Did you get her through Cupid's Corner ?

Do you have any LastException files in Documents\Electronic Arts\The Sims 4 ?

•  Delete the ones you have
• Trigger the error again
• Check if new ones are created
• If that is the case, please copy/paste the content here. You can open the file with any text editor.

Deleting the file won't fix your issue. Posting the info is meant for troubleshooting. 

Having this error as well- tested with and without mods, same error. LastException seems to be pointing to something to do with Royalty and Legacy's secret babies, which this pregnancy was:

Nothing special about her at all.  I created her in CAS to be a legacy founder along with her husband, who was the father of the baby.

Please follow these steps to test  your game on vanilla game with no mods/cc

• Create a backup of your save game
• Move your mods folder to the desktop
• Delete the following files from your user folder.
  •   localthumbcache
  •   Any lastException Files
  •   Any LastCrash files.
• Test a backup of your save (you will loose all cc on the save but since you created a backup you can go back to that afterwards) from before the Sim got pregnant and see if the same error occurs, then post the LE the game throws.

It would even be better to recreate the issue on a save that never had mods in. 

squeaktastic​ How did your Sim get pregnant ? Normal Woohoo Means ? Do you also have the same exception ?

Apologies, I've been dealing with a family member in the hospital, and haven't been online much.  Normal Woohoo activities.  I got a last exception one time, when she went to the hospital to (not) have the baby, but since then I haven't been able to get one to trigger.
