it says i need to extract 25 powers from the kunai cube, and according to my achivement record, its at 36 atm..

no

Some kind of bug where it starts the count when you pick up the quest. It doesn't count the ones you did before picking up the quest.

so how do i fix it? keep extracting?

Log off and log back on it worked for me in the past for some achievements

i also found extracting one more pops it as well

I also had this problem. I just kept extracting. Some people say it starts to count when you get the task, some people say that it only counts the non class related items that is extracted into the cube.

Pretty sure it wasnt/isnt counting class specific affixes...gotta be usable on all classes.

rings and amulets does not count.

36 is less than 25
