Sims 4 Balcony glitch

@VinceK7925 In your screenshot of the build we can see that there are panels of the wall missing in two places, plus it looks like light is coming through into that room at the seams. Can you please use the wall tool (like in this video) and re-trace each room in the 2nd floor, plus each balcony, then make sure all of the doors are still there (if not, please re-add them, then see if the issue remains. Please let us know how it goes. Thanks! https://youtu.be/rx__MGVGMnc
