My child sims can't use refrigerators after i added an excessive amount of sims

So... i made a chaotic children's only village in the sims 4 with a lot of children, about 40 of them. i used the mc command center mod so that i could add more than 7 children. i also used the mod to delete the grown up. i tried to feed the kids using a refrigerator, but when i tried to make one of my child sims open it, get some peas and eat them, my sim did the animation that says that something is in the way, even though the fridge was placed in a place that sims normally would be able to use it. afterwards, my sim started glitching by t-posing and unt-posing and repeating. i fixed the glitching by removing the floor and undoing., but all of my sims were not able to use fridges anymore, i tested it on other sims too.

Mods i have installed in my game: [Mc Command center, Zulf's Kids can use spell magic, Zulf's Kids can paint, Ziplis Kids can quit school]

i tried updating my mc command center mod files and the glitch was still happening, can someone please help me with fixing this?

i haven't tested if adult sims also can't open fridges anymore.

i know it's strange that i had that idea with an overpopulated kid's only village, but i have a weird fascination with overpopulation... i literally have no idea why
