Where did my children go EA?????

Okay so this JUST started after yesterday’s update, BUT I just moved my legacy save into a new house. One mom, one dad, two pets, a boy toddler, and a girl infant. For the past day I’ve been trying to get the children’s needs up but anytime I try to bathe them or feed them or change them, my sim will not go and do the action. Sometimes they say they can’t access the area, but most of the time they just stand still and don’t even go to try. I look online and someone said to move the children out and back in. I went to move the kids in with the grandparents and now they’re NO WHERE TO BE FOUND. LIKE they have completely disappeared from the world. No one has relationships with them, and there’s no evidence of their existence even within MC Command Center. Am I crazy or did this happen with the fix yesterday??

my plan is just to restart having kids, but like I’m so frustrated. Please someone give me ANY help!
