I've gone through all the steps necessary to get to the Treehouse, but it isn't popping up the second dialogue for Milhouse and Lisa once they are sent to school. I'm nearly level 15, have tried sending them to still again, letting them sit around for a few hours, but nothing has triggered the action. Has anyone else run into this and found a way around it?
