It seems like her schedule is missing. I'm not sure how that happened, but here's a fix:
SugarCube.State.variables.girl1.schedule = {
"mon":{"7-8": "kitchen", "10-14": "bedroom", "15-17":"livingroom"},
"tue":{"7-8": "kitchen", "10-14": "bedroom", "15-17":"livingroom"},
"wed":{"7-8": "kitchen", "10-14": "bedroom", "15-17":"livingroom"},
"thu":{"7-8": "kitchen", "10-14": "bedroom", "15-17":"livingroom"},
"fri":{"7-8": "kitchen", "10-14": "bedroom", "15-17":"livingroom"},
"sat":{"7-8": "kitchen", "10-14": "bedroom", "15-17":"livingroom"},
"sun":{"7-8": "kitchen", "10-14": "bedroom", "15-17":"livingroom"}
}
Just open the console/inspect page (ctrl + shift + i), and copy paste this. Hopefully that resolves it.
