Is the Rewards box supposed to disappear after that days reward has been awarded? I was able to claim the first reward and then was not able to see the Rewards box in my inventory anymore. The next day, the Rewards box was still not there and I kept checking to see if it would come back, and it did not even though I was on for hours. Today, the Rewards box was there again, and I had to buy yesterday's reward because it was not claimed. Now the Rewards box is again not showing in my inventory, and I didn't have a chance to claim today's reward by clicking on it after my 30 minutes of game time. Is there something I'm not doing right, or is this happening to others as well?
