Children being taken away with full needs and good grades.

My household had 2 children at the time of the most recent update. The older one was an A student and their needs never dropped below yellow and I got a popup that if their grades didn't improve they would be taken away due to neglect. They aged up before they were taken away.

The younger child was a B student when they got the same popup and their needs have also never dropped below the yellow range. They went to school, became an A student, came home, did their homework and filled their needs and were still taken away due to neglect. 

I had mods and CC installed so I went to a previous save and removed mods and CC and still had the issue. I've never had this issue prior to the February 20th update.
