[FIXED] Plants shrink after harvesting/ Turns into harvestable

@malswartz I was testing something this afternoon and it reminded me of your comment. In my greenhouse my Sim grafted two plants. I was waiting to see if they would grow correctly afterward.
Before:


In a short time - maybe later that Sim day, the tiny Money Trees grew to full grown. I also noticed shortly after that (same day) suddenly over half of the plants were a pile of dirt. All of the trees were also gone (deleted) except the Money Trees. The plants that remained were one tulip plant, 2 orchids, 2 BOP, a Bonsai, and 1 UFO plant. While it was like this I sat there and watched for an entire Sim week. Nothing grew from the dirt piles. The grafted plants did not progress. The plants that were acting normal still produced harvestables and weeds, including after they were harvested:

This is a sheltered, indoor greenhouse with sprinklers, bees, and plenty of tending. I have grown in this greenhouse a great deal and never had any issues whatsoever, at any season or anything. They grow year round and wonderfully.

Another odd thing is the dirt piles are pitch black at night, but not in the day, though they're always well lit and at night the other plants' dirt is normal dirt color. Thought I would include this here in case it was of any use.

Edit:
I was just doing a different grafting test on another lot (right across the street from that lot/save), also involving sheltered plants. On this lot I did not see any of the plants reverting to a dirt pile or deleting. The grafting and re-growth behaved as normal aside from the Bird of Paradise shoot not showing up in inventory, and the plant spliced into sage doing the weird 'tiny plant with the tan area at the base thing:
Carrot grafted into Sage:

The other plants that I grafted into grew as normal:
Lemon & Pear grafted into Pomegranate:

Chrysanthemum & Lily grafted into Snowdrop:


So.... bottom line is that my initial results must have been triggered by some other factors like the greenhouse involving plants in a sunken room planted directly into the ground or some other factor. In both cases/lots there were bee hives in the areas (the greenhouse and indoor room on the second lot).
