Piccola Luce in Tartosa is buggy

idk what update it was but now with the rooms below forming the floor of certain rooms above when trying to select all and just mass paint a floor in a maxis created lot Piccola Luce, the double bedroom platform and floor interfere with vaccuming, they cannot be cleaned. if trying to edit the room and do anything that ISNT deleting the walls one by one, it deleted just a section of the room and not the whole floor based off of the room below, so it forms a section to be deleted or customized when trying to place new floor. it also seemed to break down the half walls i put up to replace the front facing walls deleted to simply finish it off, making the entire thing have to be painted either individually or dragged but not using the shift button to coverall similar walls.
