I'm having the same problem. An unmistakable change in Dragons Gem drops.
If this change isn't deliberate, please please please change it back to the way it was.
If it is deliberate,.... why? Can you just change something like that from one day to the next without even mentioning it? Isn't good for the trust in the game and purchases, if things can just be changed like this.
Please let us know one way or the other..
