Re: Sims 4 inside house walls are invisible
@latenightliz Do you have your walls set to "cutaway" rather than up or down? If so, this is normal behavior: only the exterior walls stay up, and the rest cut away to show the rooms inside. You can put the walls up whenever you want to place items, then put them down again; or you should be able to to place items even without the walls showing as long as there isn't already another item in the way.
If this isn't your issue, please post a screenshot or two showing what you see.
