Ok, right after I took the picture on the last post, I picked up my plants and I was about to go when I saw this:

For those that can’t see the picture, it shows shadows of plants that aren’t there. I’ve nicknamed it the ‘Ghost Plant’ glitch.
EDIT: I’ve realised that anybody could do this glitch! Just put your potted plants down and pick them up! There is a downside, though. The ‘invisible’ plants block the way as if their still there, so it gets a bit annoying.
