Why is the "take photo of" interaction in Sims 4 not working?

I recently bought The Sims 4 Growing Together and I really want to take family photos. I also have the Moschino pack and I'm trying to set up the tripod to take photos of the children (1 child and 2 toddlers) and the parents. When I select the option "take photo of" absolutely nothing happens. The sim who is supposed to take the photo just stands behind the camera for hours and no one poses. I managed to take a picture of the children when I managed to get them all to stand on the spot I wanted and commanded the adult sim to just take a picture. Another time I wanted to take a picture of the parents so I selected "take a picture with", the mom walked to the spot, the dad turned on the timer and walked beside her but because I had celing decorations blocking the view I couldn't take a photo. I then went into Build Mode and simply moved the ceiling decoration but left everything else untouched, but now when I select the same option the dad turns on the timer but can't walk to the spot, as if something is blocking the way. But I literally moved ONLY the ceiling decoration, I don't understand how it's impossible now to take a picture. I've seen many other people with the same issues but never saw a solution for it. Please can someone help me? This is ridiculous, all I wanted was a family picture without resorting to mods!!!!
