Lost data and Demanding Campaign

I finished the initial campaign and some of the other ones, then when I connected to a different network a couple of weeks later, I lost all my data.
Campaign uses "currency" called mana to buy elements. Different elements are required to complete campaign missions, and mana is earned by fulfilling missions. There is basically never a net mana profit. You can spend 1000 mana to buy the elements required to complete a mission, then earn 400 for completing it. This requires the player to play every day and earn small amounts of mana through the daily challenges, which are in no way challenging.
