When I try to claim any achievement I only get the message "Operation failed. Please try again later!". It started with "Four-Star Rune Tragedy" and now I have achievements piling up and the menu button blinking but I cannot claim any of them.
Steps to Reproduce:
1. I enchanted a 3-star rune with a 4-star rune and nothing happened as it should.
2. After that I enchanted a 1-star rune with a 4-star rune and "Four-Star Rune Tragedy" got unlocked as it should.
3. I clicked on the achievement to claim it.
Observed Result: I get the message "Operation failed. Please try again later!" when trying to claim this or any new achievement.
By the time of this post I have a total of 365 gems, over half a million gold, 9 fire tokens and 35 energy waiting to be claimed. As I continue playing I'm going to miss out on a LOT of resourses...
