How can a post have an overall score of +1 with 0 up and 1 down votes?
Notwithstanding the answer itself, I see 0 vote up, 1 vote down, and a final score of 1.
Steps to reproduce:
- Find a post with vote +0/-0.
- Vote up
- Cancel up-vote
- Refresh the page to see it reports a total vote of 1, and the vote splitting becomes +0/-1.
So now the votes are 0 up, 0 down. We can infer from the timing allowed on vote cancellation that in some cases, a single up-vote, cancelled, produces a "temporary down-vote" which is cached and doesn't get removed for about a day. The sum total of votes remains unchanged post cancellation (and thus erroneous) and the vote detail is also erroneous.
