Daycare making no sense

[Devynn]

My sim runs a daycare and she's at level 5. Well the last two working days the kids' parents never showed up. The first time she was watching only one child so the kid just spent the night and went to school in the morning, no big deal. The second time there were 3 toddlers, 2 children, and a problem child. The parents never showed up. I had just fed all the kids dinner and the two normal children showed themselves to bed and I was offering the problem child a bedtime story. His mood was "going south" and he was having no fun. (Which I really didn't care he broke just about everything in my house) when all of a sudden he vanished and my sim's license was revoked because a child starved to death under her care. Turns out it was the problem child.... but he had just eaten not even a sim hour before.

Is all this normal or is my daycare glitched somehow?
