Why did all my boosters dissapear??

I dont know how many or if i recieved gold bars, but thanks a lot! I cant buy any boosters with gold bars, is there any chance i get all of my old boosters back? right now in the game its not really possible to collect boosters like before, because of all the unlimited boosters for a short period of time. (Which is great) but now when those end i cant use anything anymore and since i did nothing like updating, the game didnt crash etc i am dissapointed that i lost all of them and not have them all back.. please let me know if i need to do anything or if it is possible to fix this
