Have you tried putting her in her career outfit before trying it? Double check that she doesn't have 10 career outfits, too. Can your family afford to buy the graveyard and replace the mausoleum?
I bought the graveyard and replaced the mausoleum, and changed her into work clothes, and she went to work just fine. Thank you so much! Interestingly she automatically got dressed for work with the new mausoleum. I saved a copy just before the property purchase so will have a look to see if getting dressed alone would've worked.
Two odd things though: I can't collect money from the property as it doesn't meet minimum requirements - says it's missing a mausoleum ?!?!? It doesn't matter to me as I only want to fulfil the challenge requirements and am not worrying about every penny but thought it strange.
Also I had my teen drink a liquid job booster elixir before going to work one day and her performance was actually worse than on other days with otherwise identical circumstances has this happened to anyone else?
