Lost chest during iOS update

Not a huge deal, but it does take some time to grind for the gold to get the chests and I was a little bummed when, after updating, I had no chest to open but the gold was gone

Have you relogged in game Center after the update?

Sometimes updates resets settings and you have to again log in to some services like game Center.
