Although the vast majority of trades are successful, once in a while the server might lag and an error can occur. If this happen, it will take some time to retrieve your Gold. Please be patient. Don't repeat your purchase as your last transaction will still be ongoing. Some gold are delivered to Items-My Items- Resources, so if you don��t receive all please check your items first. Meanwhile, you can restart the app to check your Gold. Contact us and provide your order No. if you don't receive your Gold after a long period of time.
