I started a new save after installing the patch and Eco Lifestyle. My sim has been building up a garden since then and it worked fine, except the visual glitch on the sage and basil. I think I once noticed quality reset to normal after travelling but returned to what it was the next day.
Yesterday I played the end of sim week 8 and had my sim stay over at a friend's house for New Years Eve. When I had her travel home (at 3AM, before it officially became Spring), the sheltered plants that had come into season overnight had been reduced to mounds of dirt. I moved them outside as they were supposed to be in season, but after a day or so nothing had happened. I found that putting them in the household inventory and then back in game returned them to their grown state. So for me it was easily fixable.
This hadn't happened with any change of season before, so it's either related to my sim not being on the lot or the plants being sheltered, or both. I don't recall whether I built the greenhouse before or after it became Winter. I'll see what happens once I move on to Summer and my sim stays at home.
