I had a vote on a topic, but later removed it; the number of votes is reflected correctly. However, the details of who voted still includes me:
…and thus shows thirteen people.
I’m not sure if this affects just the currently-logged in user, or all users who’ve removed their votes.
It looks as though the query to determine who voted happens here, but when I run that query directly using Data Explorer, my name isn’t included. I’ve also validated that the post in question has no votes
or votes_archive
records in user_custom_fields
for my user, so I suspect this is a JS display issue.
