In ancient times to make this achievement worth 61

In ancient times to make this achievement worth 61.000 , not counting the contribution. And gave him a 24-hour unreal drop. But when I saved 61 thousand, the achievement was worth 121.000 . And when I was 121 thousand, that's again not enough.
Finally I have enough coins and I started achievement. That's a dream come true! But before he finished, there was a separation of the boosters.
And now have one 8-hour unreal drop.
so Much time spent... so Much effort and coins. Unpleasant, to put it mildly.
