Thanks everyone who helped me,I deleted my farm hero's saga game because it would not open,then reinstalled,my game level was saved,was up to 869,so very thankful!!!
My app crashes all the time, I have to reinstall and each time you reinstall you lose all your saved boosters. This really sucks but now I don't save up my boosters I just use them because the app crashes at least two or three times a month.
