Latest android version. Miss Devis tells Kelly to come back on Saturday (second time) but I forgot to go to the college on that second Saturday. Instead I worked in the cafe all day. No reminder to go to the college so by the time I was done at the cafe it was night time. I tried to go home and it tells me I should go to college as requested. But when I try to go to the college, it says it's too late.
So can't go home because it says I need to go to the college but can't go to the college because it's too late.
Luckily, I hadn't saved a new file and simply quit the game and loaded an older save and went to the college before it was too late but the game should have taken this scenario into account because otherwise, you end up in an endless loop.
