I've encountered several bugs; I'm wondering if anyone else is experiencing the same.

  1. Achievements: I have unlocked the Warlord and Strategy achievements (complete 12 Attack and 12 Defense achievements, respectively) but cannot collect the reward. The button animates as if I clicked it, but nothing happens. That's 2 cards, 400 coins and 70 prisms that I can't get to!
  2. Retrying an attack: Sometimes, when all my soldiers are killed, I cannot retry. I have plenty of prisms available, but when I tap the retry button, nothing happens. As above, it animates as though it recognized my input, but it just sits there after, and the only option left is to return to my base.

Overall, I really like this game. Most of the games I play on my phone only last a week or two before I get tired of them, but I really enjoy the mechanics of the game.
