Re: Latest espansion version

@03816  If your game is fully updated, so are all your expansions.  The patch data for packs is part of the base game files, specifically here:

[install location]\The Sims 4\Delta

You'll see a folder for each pack that exists, whether you've installed it or not.  If you were to delete one of these folders, repairing the game would restore it.  Any update or repair will download the newest-available version of each folder if it's not already present.
