All lives are gone

RdG59

Suddenly all my lives are gone (at least 200). And also all my extra gadgets (candy hammer and more).

Can I get them back?

Hi and Welcome to the King

you update Facebook, change your profile, reinstall the Facebook app or even update its app software, those Facebook notifications may get lost, as they've been delivered and cleared from the queue. While it is possible to store in-game messages from your friends, due to these factors outside our control, we cannot guarantee that they will remain on your device indefinitely.

Lives can also be lost through an update to the game, your own device or by restarting your device, which clears a certain amount of memory, depending on your device. 

Check also the page here about the Lives.
