Beds obstructed by signs and ladders

Beds are now obstructed by signs and ladders when they where not previously. This happens when there is a sign or ladder in the surrounding spaces of the bed, example having a bed surrounded by three walls and the open space having signs, the bed indicates obstructed, also when a bed is elevated and a ladder is placed diagonally (top left diagonally in my case) the bed indicates it is obstructed.
