Game won't update to most recent version and is stuck in an old one

@ugsage  If you've reinstalled Sims 4, you'll have the newest version by definition.  What makes you think the game isn't updated?  If you're looking at gameversion.txt, delete it and let the game create a new one, then check that version.  You can also find the game version at the Main Menu, in the lower-right corner of the screen.

Let me know what version you see in both places as well as if there are any features you're missing in-game that make you think Sims 4 isn't updated.
