Why didn't I get points?

Question

In this question, my answer got BA'ed. I had 1,702 points before that, and I didn't get my 20 points. I did not get downvoted twice around that time.

Answer 1

Possibilities:

• BA was unselected on a different answer you posted.
• Two up-votes were removed from your posts.
• Your memory was wrong on this occasion.

All of these possibilities are more likely than this being an issue with the software.
