I have been playing the campaign and up untill now completing the first 3 levels with 3 stars unlocked the next campaign level. But after completing the 4th level with 3 stars nothing new has unlocked. I've double checked and it says I have completed it on normal difficulty with 3 stars and I had a total of 12 stars. I then completed the bonus levels on level 1 and 2 so have a total of 16 stars but still can't play on level 5.
I'm playing the game on an iPad 2 and it's the full payed version not lite or anything. Is this supposed to happen or is something going wrong, I have a feeling it's glitched somehow and should be letting me play level 5 right now.
Cheers
Danny
