I have a similar problem. Tried making a family with two adults, one child, and one toddler, and as soon as I moved them into a lot, the child and toddler vanished. Same thing happened to my boyfriend when he tried playing it the other night. Things run smoothly for me otherwise, but there is no way to play children or toddlers because they just vanish when I load the lot. Hopefully this is resolved soon 🙏
And pets are the same way if they are made in CAS with a family. Pets will load if they enter the lot or if it’s like the spectral cat from a witch sim, but otherwise, trying to make them with a family will cause them to simply vanish when I load the lot, same deal with children and toddlers.
