As of today, the 'Other action' option in the First Answers, First Questions and Late Answer queues is not selected automatically anymore after performing a (qualifying) action, such as
- voting on the post
- editing the post
- flagging the post
- upvoting a comment
This used to be the case, at least earlier today, and also in the old versions of the First Posts and Late Answers queue, where a qualifying action automatically enabled the 'I'm Done' button.
