Reloading family after not saving, causing game breaking bug

Hello,

So I had birthday party for my baby and she aged into toddler,  and my toddler aged into child. But something happened on birthday party that i didnt like and I quit household and reload it from time BEFORE birthday party. My baby should be still baby but no she was toddler, and same for my toddler she was child. But game behaved like they were still baby and toddler so game wasnt programed that toddler having baby animation and it was glitching and blicking like crazy and I couldnt interact with it. Same for toddler, child isnt programed to have animations like toddler.

I was really furious and I rage quit.
