When an automated door closes, it's supposed to push out the items within the door. This works when placing tiles and closing vertical mechanized doors; however, when the door is placed in a horizontal fashion next to a wall, the door does not push the items within it. Instead, the door will push an item to the one cell and trap the item within the door when it should instead be pushed two spaces to the left. I've added four images to show how the door behaves and what is expected.
Here an egg is on the far left of a door when the door is open.
The door closes and the egg is pushed 2 tiles to the right (as expected).
Here an egg is placed to the far right of the door:
Instead of being pushed two tiles right and out of the doorway, the egg gets trapped inside of the door and only moved 1 tile. I had to open the door back up to show the new position of the egg as with the door closed, you can't see or click the egg.
