Hey there, I don't have the Amy achievement though I did her quests as I was a newbie. Now I'm too rich to make one of her quests... What's wrong with that achievement?

You need below 500K to do her quests, if I remember correctly.

Possible, but why didn't I get the achievement as I did the quests as a newbie?

Because the achievement isn't retroactive. :) The quests you did before the achievement was introduced don't count.

They're not retroactive. You'll have to do them again as the achievements did not exist when you did them or you would have gotten them. :)

Ah, thank you =)
