My sim randomly disappeared even though I had him saved to the gallery

[OkaeDen02]

Product: The Sims 4
Platform:Mac
I want to talk about something you don't mention above:
How accessible is the current experience? It's overall fine
Summarize what in the product is difficult to use. It's not difficult to use but, MY SIM RANDOMLY DISSAPEARED after adding mods and I don't understand. I saved everything and he should at least be in the gallery but he's not. He's also not homeless he's a teen.
How is this making it more difficult? I'm doing the 100 baby challenge and this makes that significantly more difficult because he's also a source of income.
How can we reproduce this experience? tell me how to get my son armani back

‌

tell me how the hell to fix this please
