Hi! I've only just downloaded sims 4 after having a real long break from sims 3 and I am finding it a little difficult. I am trying to renovate a house, and it won't let me put floor tiles on the next level up, even though there should be enough support below. The only way I've worked out how to do it is to put a set room deck on it, then replace the floor tiles with what I wanted. Is that the only way?
