no way to get it back; they have a no-refund policy !! And they won't be giving us a confirm button (it would be a failsafe against accidental spending). I spent 50 gold by mistake by tapping on the life dragon in the market. I know of people who wasted 300+ gold on buying maps for expansion, or on finishing the expansion, and one person actually wasted 760 gold

beware, the new trading and spell buildings present us with yet MORE gold traps, so we should all be wary of this.
