So the situation is.
I recently reinstalled Sims 3 in preperation for pets. Before doing so I shared my household in two files, one with the sims, the other with both.
I cannot install these files.
Upon opening them in the Launcher, they apparently run through the installation process in the Downloads folder without issue. Checking the installed content afterwards confirms this. Yet in game they are nowhere to be seen. Furthermore when the game is shut down and the launcher reopened, the household has removed itself from the installed content and reappeared 'uninstalled' in the downloads folder. As if I never touched it.
Further testing revealed that if I ran through the apparent fake install, then tried to uninstall from the installed content, there would be an error stating the package could not be found. Also, I have tried other households from friend who has the game, they behave exactly the same.
Does anyone know how to fix this?
Cheers.
