Issue with tray files for households and lots
I keep a backup of my households, lots and rooms by copying the tray files corresponding with each one into its own folder elsewhere on my hard drive/online.
Today I copied a lot into the "Sims 4 > tray" folder and it didn't appear in my library in-game as it always has in the past. I thought perhaps it was just an issue with this one, so I tried others and they didn't work either.
I attempted the same with various households only to encounter the same problem.
Strangely however, when I tried with a room, it loaded just fine, only adding to my confusion.
I removed all of my mods and tried again, but still had the same issue. I uninstalled and reinstalled the entire game, but still the problem persists.
Then, even more strangely, when I just checked my library a moment ago one of the households I'd copied the tray files for earlier is showing, despite not currently being in my tray files.
As a note: I haven't played in a while, and there have been at least a couple of patches since then. Not sure if it's related to those.
