Ideas
I logged into The Sims 4 after the most recent update and immediately noticed that all of the photographs placed on walls were displaying as completely black images. I exited the game without saving, cleared my cache, including the localthumbcache file, and logged back in to check again. I then loaded a different household to confirm whether it was isolated to one lot, and the same issue occurred there as well, all wall mounted photos were black. I exited the game again without saving to avoid overwriting any data. Because this issue affects photographs across multiple households and appears tied to the latest patch, I will not be continuing to play or save my game until another update is released that resolves this bug, as these photos represent years of in game memories and progress.
