Hi Paul, it sounds like the bonus map gold chest issue occurred several days ago. It was a minor mis-configuration issue we missed during testing that may rarely cause a brown chest to appear as golden chest, then disappearing at the end because failing the server check. Please provide the approximate time of that battle and your game ID (found in Menu--Invite Bonus--My ID) so that we can look into it.
Enjoy the game!
