I've lost my boosters

Question

I was receiving my gift with Rami when suddenly my screen froze on my iPhone, I waited like 2 minutes and still frozen, so I closed the app, and when I opened and my boosters disappear, also my ranking, Rami and everything else, only my level 2251 and my gold bars still being the same, I had turned off my iPhone, and turned on again and I only could recover my ranking, my level 2251 continue existing, Rami appeared again, but my boosters never came back =( I have just one because I won it on the roulette.I had never synchronize the game with my email, nor Facebook, but im worried that if I synchronize now, I wold never recover my boosters.

PLEASE HELP!! I want my boosters back =(

Yes you can lose all your boosters at any time when playing on a mobile device.  They encourage you to use them as you play the game instead of accumulating them.  Believe me they are also accumulated on my mobile devices and I am aware that if the game crashes they are all gone.

So it doesn't matter if I save my progress and synchronize it with my mail? If my device crash I will lost my boosters no matter what?

Hi Paty,

Please note that the boosters are saved to your device and not the game data, so you can use them when offline too. This does mean that any updates, crashes or device changes can cause these items to be lost. For this reason, we do not recommend storing too many of the won boosters as these can indeed be lost unlike Gold Bars.
