I have no issues with cloud saving and I always use it.
<now if the game crashes or something but I don't mod and my game hasn't crashed for a very long time>

North Am near NYC so don't know if that helps in my case being near servers or whatever.. IDK

Now recently it won't show it syncing when I close the game. Normally I can hover my mouse over the tray icon and see it syncing but it has not been. It does sync quickly when I start the game so that is fine.. as long as it syncs each time I don't care when and don't need it both times.

This same thing has been happening with another game I play also.
For a while it would sync when closed and opened. On my other game the syncs were long so it was a bit of a pain. But recently for both games the sync has only been happening on start up.

Not sure if this is your issue but something to watch for.
