If a plant is not fully watered, the water droplet picture will show up on the screen no matter how far you are. The water droplets from my farm were still visible on my screen from the beach.

This happened to me again today

It happened again this morning. I think part of it might be that these are the plants/empty crop spots near the edges of my field of view and for some reason when I look away, they just don't realize? If I go back up to the crop it will go away, but if I don't it will remain on screen for the entire day and be visible from any distance.

This happened to me today - an unfinished watering droplet followed me around town. I was finally able to get a screen print and will place in rainybug photos.

For some reason I can't edit my previous comment, but I wanted to add a note. In this specific case, it was a tilled spot that had no seed planted.
