When this happens to me, I have to check the settings on my device and make sure I am online. Sometimes your internet might drop. You may have to restart your game, but the rewards usually come up the next time you play.
@Deryck, that avatar is my Facebook profile photo. The single person at 6140 is a Facebook friend. I’m done with all the levels and am waiting for more to be available next week. How do I make my avatar an avatar instead of my Facebook photo, or is that possible?
I didn’t even know you could do this. I never tried, since I assumed you would lose a life if you opened a level. It does seem more fair to have it this way. And I’m not just saying that because I didn’t know you could do it!
