The elevator problem is because the shafts the elevator uses shifted. Rebuilding the elevator shaft in all your buildings with the problem will fix them. Unfortunately saving the building to the library and planning to use it elsewhere rarely works for some simmers as that shift gets even worse when we upload the building then redownload them into our game, it will often shift again. Must be something in the download/upload process. You can see what I mean by using landscape paint in your sims yard - then upload the house to your studio - redownload it from your studio back into your game - and everywhere you have terraine paint will have shifted off center - generally toward the right. It is extremely annoying - but in the case of terraine paint doesn't cause a problem , but does cause problems with elevators, circular stairs, and stacked stair amoung a few other things. I have noticed every ep since LN it gets a little worse and shifts as little bit more to the right.
I have no solution but rebuilding anything you download, remove the stairs, then put them back in, and rebuild the elevator shafts - or in my case refuse to have any buildings with elevators. Angers me, as I enjoy the fun parts of elevatos - like the clumpsy sims are funny in elevator.
