We're having a maintenance break shortly: the Attack boost is coming to an end but we're extending the resource boost until further notice, so you can continue boosting your Gold Mines, Elixir Pumps and Dark Elixir Drills for one gem each still.

In the meantime, we will continue looking into the whole resource system (and not only in terms of saving), and how we can improve the game economy overall. We'll let you know about those improvements as soon as possible.

As usual, we'll do our best to keep the maintenance short and sweet! /edit: maintenance complete!
