This doesn’t solve the problem though, we should be able to have double volume rooms, just about every house I’ve ever built on sims has atleast 2/3 tiles around the staircase that for aesthetic purposes is fenced and then I delete the floor inside the fence. This has always worked, even when we first got the ability to manipulate staircases. Some houses obviously go to the extreme and have entire rooms deleted around stairs to create double floor stairwells and sometimes even triple, and this has always been the way we do it, you apply the fence and the game automatically removes the fence from in front of the stairs and as I mentioned this has been done countless times. Why would they patch the game in such a way that it breaks the way we build houses, I just checked a few of my houses i saved to my library and none of them have functional stairs anymore ...
