Corrupted files

@jeanmarie618  Capping fps is easy enough.  Right-click on your desktop, select the Nvidia Control Panel, choose Manage 3D Settings > Program settings, and pick TS3.exe from the list.  (You want TS3.exe, which is for Origin installs, as opposed to TS3W.exe, which is for disc or Steam installs.)  Scroll down to "Vertical sync" and set it to Adaptive.  Enable triple buffering too, just above vertical sync.  These settings only apply in fullscreen mode.

In case you ever want to play in windowed mode, in the same list of options there's a Max Frame Rate setting, which you can set to 60.  This works in fullscreen and windowed modes, but it's best to use vertical sync and triple buffering in fullscreen mode because they also help prevent graphical issues like screen tearing.

As for the store items, they simply don't load sometimes for no apparent reason.  If you see it happen again and accidentally save, you can always load the backup save instead.  It's also a good idea to get into the habit of saving first, then quitting without saving as a separate step.  In addition to making easier to avoid clicking "save and quit" when you don't intend to, the advantage is if the save process fails, you see it happen and can do something about it rather than the game going straight to "quit."
