Farm Merge Valley not saving progress

Slightly unrelated to the current issue, but seems like a good place to share my suggestion:

I try to always Save (where available) and Quit a game if I am not actively playing. In the past I have had problems where it times out and doesn't tell you until AFTER you resume play, and then it restarts, taking your latest progress with it. If I am interrupted unexpectedly and come back, I will finish any open game and cross my fingers and hope it saves. If, however, I left Pogo open on a game's main page for more than a couple of minutes I immediately exit and re-start (not just refresh the page), just to make sure nothing is silently disconnected. For the most part (except as I reported 2 days ago in this thread) this helps prevent the agony of getting the "Unfortunately, your progress could not be saved. Do you want to try saving it again?" blue box.

What happened to me two days ago had NO messages like this, my progress was just rolled back to an earlier session of playing the game.
