Although I don't feel the badge system is core to the success of the forum, when there are related problems or inconsistencies they tend to cause frustration and annoyance. Myself, I've run into the same issues described in Some User Badges Lost and also wondered about broken or confusing requirements and triggers (e.g. [SOLVED] Site Badges - Where are the tutorials).
Recently, I became curious about a badge with no awardees, Out of Love, whose requirement is to "use all 50 of your daily likes". Surely someone should have this by now, given the quality of content on the forum.
So I tried an experiment... Since I haven't been as encouraging as I could have in the past , I had a lot of bookmarked posts and topics that were worthy of "likes". It didn't take long going through these before I used up my likes and got the message "You used up your likes. Please wait NN hours and try again."
Based on some Discourse forum comments, one needs to wait until the NN hours have passed and then the system will recheck the badge requirements. But even after waiting, nothing happened. Now as I stated above, getting badges isn't that important but the annoyances are real.
Has anyone else run into this or similar issues? Are there some badges that just don't "pop"?
