Well at the risk of jinxing it, I think the update might have sorted it out!!! I've saved, exited, and come back a couple times now, and all my plants are still there and in the spots where I left them :D :D
(I'm also loving the new rainbow pots)
ok, it sounds like it might be the double instances of the same stand bug coming back. Our main programmer is on a minibreak but will be back next week so hopefully we can get this sorted soon. Thank you so much for letting us know what is going on. One quick question, is the second apartment unlocking for you? That is another bug that just came up today. (Also, feel free to join our discord to share any screen shots of bugs-it's very helpful!)
