The sims legacy household disappear
When I start up my game the neighborhood is empty. I tried this solution Sims 1 Legacy empty neighborhood | EA Forums - 11892990 but it doesn't work for me since all my Userdata already was there. Wh...
Amurcute The workaround you linked only helps for neighborhood 1. Try moving over all the other UserData folders too, like this:
TS1 Legacy - No neighbourhoods on startup and crashes without warnings | EA Forums - 11893006
If that doesn't help, please start over by removing the entire Sims 25 folder from Saved Games, launching the game to spawn a new one, and copying over the data again. You don't need to spend much time creating new sims, just long enough to make one or two to place on a random lot.
This shouldn't have anything to with where your game is installed.
