Gate won't add to fence

Product: The Sims 4
Platform:Mac
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.69.59.1220
What expansions, game packs, and stuff packs do you have installed? eco lifestyle, discover university, island living, get famous, seasons, cats and dogs, strangerville, parenthood, vampires, dine out, outdoor retreat, tiny living, my first pet, laundry day, vintage glamour, backyard and perfect patio, city living, get to work, get together, snowy escape, jungle adventure, realm of magic, spa day, Moschino, Movie Hangout, Nifty Knitting
Steps: How can we find the bug ourselves? When I go to add a gate to a fence the gate hovers over the fence and when I click it says "must be against a fence" (I have tried several gates with several fences at different heights).
What happens when the bug occurs? Gate cannot be placed and doesn't display fence as it's being placed, distorting the fence. If placed in debug/cheat mode, it does place, but doesn't show.
What do you expect to see? The gate should go onto the fence like a door does to a wall.
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure 

I build a brand new lot from scratch. I don't have any mods and most of the packs. No platforms have been placed. I've tried removing the wall, removing the room, re-adding the room, (both with and without walls), the wall itself and the fence. I've tried base game fences with gates as well as packs, though the one I'm hoping to place is from Get Famous. 

When I've tried to place the gate, it "interlaces" with fence and doesn't place with the error: "Must be against a fence". I've also tried placing this in cheat mode and it will be placed, but it doesn't show. I've replaced the fence with a wall and have been able to place a door.

I would demolish the lot, except that I haven't been able to get my library uploads working either. I've tried leaving the lot and going back into it, and even exiting the game and returning. Nada.
