I am having a similar issue. I created a new topic containing this information originally here, but I was redirected to this forum.
Product: The Sims 4
Platform: PC
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? 1.77.131.1030
What expansions, game packs, and stuff packs do you have installed? Expansion Packs: Cats and Dogs, City Living, Cottage Living, Eco Lifestyle, Get Famous, Get to Work, Get Together, Island Living, Seasons Game Packs: Dine Out, Outdoor Retreat, Parenthood, Realm of Magic, Spa Day, Vampires Stuff Packs: Bowling Night, Cool Kitchen, Fitness Stuff, Luxury Party, Movie Hangout, Paranormal, Perfect Patio, Romantic Garden, Spooky, Tiny Living, Vintage Glamour
Steps: How can we find the bug ourselves? I believe the bug occurred as a result of the pond patch last week, prior to cottage living's release.
What happens when the bug occurs? It's a graphical glitch.
What do you expect to see? Lots that load correctly visually.
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? Yes
Please describe the patch or change you made. I believe it was after the patch Maxis released for ponds, that allows you to add ducks and create more custom ponds.
I've attached screenshots of the graphic errors I'm seeing now. Prior to this week's patch, I was not experiencing this problem. I have already attempted to "repair" my game via the origin portal interface, and I have done a fresh uninstall and reinstall of the pack in question (Eco Lifestyle). I have also updated my graphics drivers.
