No Gardening Opportunities

I'll keep retrying to reset the sim. I did it three times. I've done it twice since, to no avail. Meanwhile, the second son got married just after his girlfriend aged up and gained the Green Thumb trait (actually it was cat (ugh) lover but I couldn't let that stand). I sent her for a gardening class the next day and she spent all day in the garden 'tending'. Already she has a gardening opportunity (Great Plums). She'd just harvested the first plums from the perfect tree.
