Love it but....

I just recently started playing this game and I love it so much, but this morning I woke up and saw that 16 diamonds are missing! I havent used them for anything and I would know because it always ask to tap again to confirm, anyone else have diamonds just disappear? Not cool! I was saving those up! Please respond! What can we do?
