Comment master badge
"leave 5 comments with at least 5 upvotes for each" I did it, sure, and even with 7 comments which have more than 10 upvotes each, I don't have the badge... why ?
Common bug... Wait a few days or report it through feedback (that's what i did...)
"a few days" ==> one month XD ok I will report it, thanks :)
wait, I'm watching all of your comments with my tricks
where you made the comment, in lesson/quiz or in code?
you have 6 comment on lesson/quiz with more than 5 upvotes
in lessons, in all
and so I must have the badge ?
it depend on you. comment master badge will give 10xp or 20xp for you (if it not wrong)
