Thanks for the reply. I thought it might be confusing. I had a hard time trying to phrase the question. Attached are screen shots from a game played on a PC and a game being played on an android tablet. Both Piggy Banks have been bought 7 times, which is what I meant by "level 7". I wish I had said it that way the first time.
Our Game Studios are constantly adapting our games by introducing and testing new features, gameplay or concepts. The tests sometimes can be between player groups or devices. Before any change is implemented a randomly chosen group of players is selected to trial the feature, and based upon how the change is viewed we then decide whether the change is one we want to adopt or not.
This is why you are seeing two different Piggy Banks. Thankfully Gold Bars sync between devices, so if you purchase the Piggy Bank from one device, those Gold Bars will show up in your other device too.
