Mine 20 times in grade 1 nodes.. I did this no achievement..
Unless I have to stop mining after each swing?!
NVM: There must be a serious bug with this.
I mined over 40 times before getting the 20 time achievement.
What i did was initiate gather mini game > cancel > repeat and then it unlocked after 15 times.
This means that you need to initiate gathering 20 times, not gather successfuly 20 times
