Sim Died but toddler did not go to family in will

So my sim made a will, leaving money, heirlooms, and her toddler son to a family member. She passed away, and grims message appeared. I chose to make her free roaming. I got the alert that she was the last sim in the house and had to save and go to manage worlds. I then logged into the family that got all the will items. They got the will, read it aloud. They got their money and heirloom items, but no toddler. I even checked household management from manage worlds. No toddler to be found. I do have mods, but I have updated every one since 11/2, and I can’t exactly go back and try to replicate this. She’s gone, and it forced a save.
