Sorry for any inconvenience experienced by this issue. Chest opening should be stable now. The only thing lost is gold from normal Silver Chests. If you check your play history with "P" you can see what you got. If you require further help, you can put in a help ticket using the "Help and Support" link in the footer of the game.
