Booster lost

@SOHANI - hello and welcome to our community!  I am sorry to hear that you lost all your boosters.  Did you de-install and re-install your game?  Maybe because you got a new phone/tablet etc. or you had some sort of problem that caused the platform you are playing on to crash?  If for any reason your game has to be reloaded/re-installed - then you will lose all saved boosters and lives, because those items are saved locally on whatever platform you are playing on. Your progress in the game and your gold bars can be restored but your lives and boosters cannot.
I had that problem and just had to start all over building up my stash of boosters.  Luckily there are various things available to do this including the daily calendar and daily spin a wheel and daily quests as well as collecting sugar drops and participating in the sugar track.
