Disappearing gems

I have actually. I’ve got so many odd/stupid things happen to me in this game.

I first noticed missing gems about a week ago. I had just received gems for doing the arena and popping 30 pigs. That put my total at the time to 93. I play the arena again. Turn the game off. Come back later and receive 3 more gems from the 30 minute thing. I noticed my total was 76. I did a double take and figured that maybe I had 73 instead of 93. But I was sure it was 93. The next time I played was the next day. I received 3 more gems. My total was now 56. I then knew that my total was changing. Since then I’ve noticed that is has changed 4 more times. I was up to 200 and some gems at one point and it dropped to 160 something and I hadn’t used any.
