@petitenerd. Just looking into this issue. Would it be possible to get your save folder from Documents > Electronic Arts > The Sims 4 and the name of the Sim with the fertilizer?
Of course. Save is here: https://www.dropbox.com/s/zsqxgu5y6o6zy0b/saves.zip?dl=0
The sim with the fertilizer is called Elijah Holiday and lives in the 'Little Summer' residence in Willow Creek.
