Noticed this bug when placing the furniture in a room, when the Jar is in this orientation and is turned on, it disappears at the end of the animation (when the jar is full) for a few seconds. It is invisible and unclickable for a few seconds and then appears again and restarts the animation. No problems when animation is turned off or in any other orientation as far as I could see. Nothing gamebreaking or anything, just thought was weird/interesting.
