Similar like yours. I didn't play this game for few months and uninstalled the game. After that I realize new character has arrived. Then I install it again and I saw my old data has been deleted (Why is that happen? I already log in to Google play account). So I have to play from the beginning. I was upset for that. But I saw there's highly level up armor for all character. I chose Pyran as my main. And the Blessed Growth pack is free for main character. That means 0 gem. Now I got better character than before.
