This is the second time I've passed a level, you click the next button to go to the next level, the game randomly closes and when you reopen the level is incomplete and you have to do it again!!
SO so so annoying - this was Level 46.

Hi kolju! We're sorry to hear about this.

This can sometimes occur due to a "Sync Error". When this happens, you may notice a loss of recently completed levels or energy. This usually happens because your game wasn't properly synced up to our servers and has reverted a couple minutes back to a previous save of your progress.

Unfortunately, we are unable to restore levels or energy during Sync Errors. We sincerely apologize for any inconvenience.

This game crashes a lot. I'm on an iPad 1
This games requires an IOS version of 4.3 or higher.
Sync your ipad with itunes and make sure you have the most current IOS version.
I am not sure what the highest version if for and Ipad 1.
If the Ipad will not update to version 4.3, you may experience issuing when playing.
Try restarting your device before playing and you may want to remove any applications you are no longer using . This may help the game run smoother.

Ah ha - it has been a bug:

Hey everyone, we believe we have located one of the main causes of this issue and the occurrences of these crashes should be drastically reduced in the next version update. In the meantime, we suggest you try tapping the "X" instead of "Next" to continue to the next level. Thanks for your patience while we juiced these nasty bugs!
