On Meta, sometimes we report bugs, and they get responded to by staff, with PRs to fix the bug we reported.
However, if the staff member didn’t like the topic post, no badge is awarded, even though it has been acknowledged and fixed accordingly.
Perhaps a change in the SQL query? Like if a staff member replies AND the topic is closed AND a Github PR link is sent (e.g. find it from having ‘Pull requests · discourse/discourse · GitHub’ in the link that was sent by a staff member)?
I am not so familiar with the history here, but I believe the bug reporter badge is intended to be awarded when a bug report has been confirmed as a bug by the team. Doesn’t matter whether it’s been fixed yet or not.
It is true that the query only recognizes likes, not reactions. So when @lilly added 
to one of your topics it did not grant the badge. Arguably, that’s as intended. If she had confirmed the bug then she could have come back to add the 
like. But if she had used 
or some other more enthusiastic endorsement of your bug report then that’s not entirely fair.
Could also be that the person who handled the bug report didn’t think it was badge worthy? If this happens to you again feel free to DM me and I will take a look.
I see, thanks for clarifying!
I will let you know if this happens again
