Cant Delete Stairs????? (+ infinite saving screen)

(I'm sorry if this isn't the place to report bugs, I don't know where else to complain lol)

I was just building and I placed a staircase on my lot to test out swatches. I can't delete or sell it; when I try to drag and sell it, it acts like I'm trying to place it elsewhere (although it doesn't move from where I first placed it), and when I try to use the sledgehammer icon it says "nothing to delete". I now have a staircase in my front yard that I cannot get rid of lmao, and my game won't shut down because I hit save 5+ minutes ago and its still giving me a saving/loading screen. sos </3
