I have encountered a post with a weird timeline:
13:19 - Answer was posted.
13:20 - Answer was flagged as Very Low Quality.
13:35 - A Low-Quality review task was created.
13:36 - Answer was flagged as Not An Answer.
13:39 - Answer was accepted.
13:40 - Review task was invalidated.
13:44 - Answer was flagged as Not An Answer.
18:18 - Answer was edited, marking the Very Low Quality flag helpful.
The two Not An Answer flags are still pending, and now need a moderator to intervene. So I'm wondering, does accepting an answer invalidate a Low Quality review task?
