Missing homework

every day I had my teen do her homework then when completed I make her put it back n the envantory so I can find it again, but on this I looked in her inventory it was missing, so I looked around the house all there was 1 book called something like Orbital whatever? As she completed her homework at the Addams family house was to travel I picked the one she knew Mortasa, then got to the travel she was alone without her. That was the whole purpose to see if Davina to to get into the Addams house with one of the family but that was no good as not able to get in as it be locked. I know I asked her to put t in the envantory. Now Davina went to high school and no homework completed. I wanted her to get an A graid then I was going to then age her up with a birthday cake then get her a job as a scientist. Well anothe homework book appear when she comes home from school?
