Under investigation by the game team
When opening chests on Xbox you may find additional gold, troops or other rewards only to find that they are not in your game elsewhere. In the Rewards List after opening chests a visual issue occurs making it seem like more rewards are being earned than intended. For example, in most chests you are only meant to earn one traitstone but instead more than one traitstone per chest is being given, or you may be receiving more Glory than normal.
Fixing the problem
This is a visual issue only, and whilst you it may appear as if you are missing out on some items, the correct amount of resources are still given - it will just appear that you are getting extra. The standard base of rewards are still received.
