I had the same problem with the walker and play pen. I tried everything mentione above and none worked. I did find a way, although not great. I had one member of the household move out with the toddler. I paused as soon as the game finished the move, put my camera on their house and watched until the adult went into the house with the toddler. I went to edit town and evicted the new household and merged them back into my family's house. It worked but unfortunately the imaginary friend that the toddler had is gone. I have had this happen a few times now so I don't use the new swing, playpen or walker ☹️ Those items were the only reason I bought Aurora Skies in the first place ☹️
