Recently this question about psychology and personal motivation came up in the delete queue. When I came across it yesterday it had 2 delete votes, and I added my own which put it at the top of the delete queue. However, today when I went in to continue help clear the clutter, it was no longer present. Out of curiosity, I searched for the question and found it still exists, but is no longer high up in the "most votes" queue, indeed (at least for me) it is not even visible in the list of questions with the most delete votes, despite having more than any of the others I can see at a given time.
Why I think this is a bug
The question linked was very popular in terms of votes (as is not uncommon of similar styled questions), it was closed as off-topic only after accruing many votes for whatever reason. My understanding of the way the queuing system on MSE works is more votes/answers with votes the more confirmations the system requests for deletion, with most ordinary ones requiring only 3. Because most ordinary questions disappear after those 3 delete votes, almost never is there a question in the queue with more than 2 standing votes, waiting for more to complete it, and in this case that question obtained the de-facto most of any standing vote-count, and so was put at the top of the "most votes" list and should theoretically remain there until it reaches the threshhold. The queue seemed, at the time, to sort by number of current, valid delete votes from 10k+ users, but has since disappeared from that same list when I try to view it.
I'm not certain if the site simply decides on a new batch after a day of MSE time passes or if this is a bug. If it is the latter how can we go about getting it addressed? Especially for pop-math questions which are far too broad for even the educators on our site, it requires many delete votes to clear out questions such as the example and we already seem to have issues efficiently deleting them.
