Some of my sims are not visible in the gallery, they all left their homes

@BUSE23  Just to be clear, your dates are listed as day-month-year, right?  I want to makes sure I'm getting the right dates.  I ask because it looks like there's nothing from July at all, but maybe you meant that you hadn't played since July and the files from that time disappeared.

Similarly, are the items that correspond to the the files in your screenshot loading in-game or not?  If you want to be absolutely sure, take everything out of Tray except for one set of items that all have exactly the same timestamp, and see whether the corresponding item loads.

Yes, my tray files are displayed in the form of day-month-year.

I created a lot of sims between April and July and made changes to existing sims. However, the new sims I created during that date range and the changes I made to existing ones are not visible.

There are only 3 save files in the game, one from 2022, one from May 2024 and December 2024 (last played).

When I look at the May record in the Load game option, the family I created appears on the screen, but this family does not appear in the library. And when I select Play in the Load game option, it does not play on any sim as if I started a new game.

I will take everything out of Tray except for one set of items that all have exactly the same timestamp, and see whether the corresponding item loads. But the problem seems to be caused by something else ☹️

@BUSE23  I'd like to know whether the sets of files from early May work in particular.  I see a few from the 3rd to the 9th, all of which look like they could be complete sets of files, but it's impossible to tell from here.  Sometimes loading just one set of files works when trying to load all your content does not.
