Not certain if this is a bug, or if it is by design. When I have an object selected, such as a bed, drain, or desk, it automatically changes to jail door when the cursor touches a wall. While the cursor is on a wall tile, it only allows me to select objects in the menu that can be attached to a wall tile, such as the previously mentioned jail door, window, staff door, or any other door.
Upon exiting the wall tile and moving to a floor tile, the 'selected object' changes to the the first item in the list of available objects.
It is extremely annoying when trying to place multiples of the same object that I want in different rooms when I have to cycle through the list every time I touch a wall.
