@Playalot --- I turned autonomy off for a few minutes. Some of my Sims went to the computer lab, but some walked out because I hadn't locked the doors yet --- by the way 7 of 8 of them are focused or very focused, and I shift clicked the mailbox when I noticed that their needs were low --- especially their fun need. Even then, they didn't feel like doing their programming.
However, the Sim below (Moira Sullivan), is standing next to "her" computer --- the 3rd one from the left that she's standing next to. I asked her to do her programming, but she canceled the action, and I don't know why. She won't do anything else on her computer, either. When I asked her to start a social media profile, she said she couldn't get to her computer --- even though, she's right next to it.
Moria next to her computer.
Then, the child in the pink pajamas (Maureen Sullivan said she can't get to the computer to go on Simpedia before school --- even though she's in the room with the computer. Autonomy off for now. (There's a kids computer room with 2 computers, which is separate from the main computer lab. The kids computer room has a door to their bedroom, the living room and the main computer lab, so I don't know why Maureen said she can't get to the computer.)
Then, Candice Sullivan (the child in the purple pajamas said she can't get from the living room to the kids computer room by going through the door, which connects them --- to go on Simpedia, as well.
Finally, I had Maureen join Candice to sit on the couch in the living room, and she was able to walk from the kids computer lab, which is directly connected to the living room by a door.
I also just found the putty because of this screenshot
