Herbalism

@elvithfax  There are a couple of bug reports about the unidentified plants in the bug reports section, I advise you to read there and see if they match your issue, or create a new bug report if they don't. Bug reports need to made on a mod and CC free game, and the report needs to be descriptive enough for it to be understood and replicated by the SimGurus.

I remember this happened to me once though, and I cleared the sims inventory of the plants, and went back to Granite Falls, picked the plants, that were then unidentified again, and identified them, while still in Granite Falls, which ticked off 10/10. Reloading the game is also a good idea when encountering issues such as this.
