I just tried the solution on this thread and it worked!! Sims 1 Legacy empty neighborhood | EA Forums - 11892990
This issue should be resolved now. For anyone still who is missing any neighborhood data (sims, lots, whatever), or whose game is crashing after the initial video but before loading into a household, you can try reseting your user data. If you're not attached to your save, please go here:
C:\Users\your username\Saved Games\Electronic Arts
and remove or rename the "The Sims 25" folder. This will reset all your in-game progress, and the files and subfolders should populate as normal now.
If you still see missing neighborhood data after a reset of the Sims 25 folder, please post in the thread below stating what is missing and what platform (EA App, Steam, Epic) you're using.
