They redid the daily puzzle last year and probably didn't fix the achievement.
I can not get this achievement

What accomplishment is it, by the way? I can't find it.
It's First, it can be obtained by commenting on the daily puzzle

It doesn't even show up in XuonChuong1902's list of available awards.
/ The space for it should be right after 1st Word.

Yeah, it's because 'First' is a hidden award, it won't appear in your awards page till you achieve it

This is the reason why there isn't a space for it. There are a number of 'secret' awards. 'Killer King' is another one. If you've been 'first' on a daily puzzle, I don't know why it didn't work.
That is first! and although i try to Comment on a daily puzzle, but it isn't work!
