so i had an issue where it didnt happen the first week i tried. just spam the advance time till sunday and i think its either noon or the afternoon she should be in there. if you try that 2 or three times and it doesnt work you can go upstairs and sleep up there and use the sleep till weekend option then try to cycle the time again.I'm stuck at the shower. It says to go to the shower on weekends + afternoon but nothing. I tried other days too.
As far as i can tell it only happens on sunday and at either noon or afternoon, one of those two.
