There's a bug of I should say an error with the way the hanging pots can be placed. I bought a plant inside a hanging pot and I could only place it halfway above the screen where I can't even see the plant, leaving me unable to take care of it
What an interesting pot placement you have discovered. While this may be a little odd to some, it is our expected behavior. In the past we put greater constraints on where a pot may hang from. This proved to be overly restrictive to some players. We agreed and opened things up to be much more flexible. Your pot placement takes advantage of that flexibility.
I trust that you could hang the pot lower in the room. It would definitely be a problem if the pot could not be hung lower or if it snapped automatically to this location and could not be moved.
You can hang them any height as long as the dot pulses when you hover over it. So it is possible to put them up quite high if you want. We added this so that you don't have to have them all hanging at the same height!
