How often does the bug occur? Often (50% - 99%)
What is your current game version number? 1.108.335.1020

Steps: How can we find the bug ourselves? It's unclear what triggers the issue.
What happens when the bug occurs? 1. Try changing the toddlers diaper on the the changing table 2. When almost finished, the toddler and parent reset, giving an LE about buffs
What do you expect to see? No reset
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure 

I can duplicate this on the save I was sent (see posts after this for more details).

Did several tests

1. Moved a random Sim in the house --> Same issue occurred
2. Tested another household with a toddler --> No issues
3. Merged the families that had a working toddler and tested toddlers/families from both households. Only the toddlers from the initial household had an issue
4. Moved one of the toddlers to another household --> Still getting the LE.
5. Switched out changing table --> Did nothing

The issue seem to be tied to the toddlers. All three have the issue.
