You might be wondering how to harvest your elder plants without some plants disappearing, I was too, but my dad told me a way that will work most of the time, a quick fix before the bug gets fixed:Okay, if you didn't get that, after you harvest your elder plant, you plant and seedling, and no plants will disappear. I tried it on all my elder plants and my plants are still there, so I'm pretty sure it works. Two things you have to be sure of: you plant a seedling after every elder plant harvested, and you have to plant the seedling after you harvest the elder plant.
