Shadow doesn't adjust on resized objects

Greetings

In  the meantime I noticed the "too large shadow" on a few other things - for example : selfmade photographs, and an object out of the dlc lovestruck : the stars-string lights attached to wooden posts.                                                                 The shadow of the modern bathtub (basegame, expensive , with upholstery) is now so big, that you are able to see it outside the exterior wall.                          I see this "too large shadows" on many objects (all original size !) , you can attach on walls.      (i didn't see them while playing longer times ago ... !)
