Mar 1, 2023 at 21:02 comment added Emil Jeřábek @Catija Thanks for the update.
Mar 1, 2023 at 20:04 comment added Catija StaffMod Hey all, I spoke with the dev looking into this and she gave me a status update - we’ve identified the problem and are looking into how to fix it. We'll have more info soon. Thanks for your patience!

Feb 28, 2023 at 17:01 comment added Emil Jeřábek Thanks for creating the queries. Out of the first 20 questions on the first list, 14 give me kitty, 6 don’t (50872, 50912, 50915, 50966, 51056, 51068). Of the second list, all questions without deleted answers that I tried work fine.
Feb 28, 2023 at 15:19 comment added Martin Sleziak If somebody wants to test this more thoroughly, one could use queries showing questions with deleted answers and all questions with counts of deleted answers within a given period. (To check whether other questions that have a deleted answer cause the same problem and whether questions with no deleted answers work fine.)
Feb 28, 2023 at 15:03 comment added Emil Jeřábek @MartinSleziak You are onto something there. I just checked an old post that I remembered to have a deleted answer by myself, and sure enough, it's broken: mathoverflow.net/questions/67015/…
Feb 28, 2023 at 14:49 comment added Emil Jeřábek To elaborate, there are at least 3 confirmed users below 10k not affected by the bug (at least at some point): mathoverflow.net/users/8250/martin-sleziak (per meta.mathoverflow.net/questions/5584/…), mathoverflow.net/users/17261/jjcale (per meta.mathoverflow.net/questions/5584/…), and mathoverflow.net/users/471160/xyc (per mathoverflow.net/posts/54735/timeline).
Feb 28, 2023 at 14:48 comment added Martin Sleziak ... and the second one. (Since the list is getting quite long.)
Feb 28, 2023 at 14:48 comment added Martin Sleziak @EmilJeřábek Since you've mentioned 10k+ users, I will add that all questions mentioned in the post have at least one deleted answer. (This is something which is different for users below and above 10k, and for users who are not logged in.) I have split this into two queries - the first one ...
Feb 28, 2023 at 14:19 comment added Emil Jeřábek I wonder whether the problem is tied to reputation, as all users so far who confirmed that they are affected by the bug have over 10K.
Feb 28, 2023 at 14:15 comment added Emil Jeřábek @MartinSleziak Both of these work fine for me, on two affected questions that I tried.
Feb 28, 2023 at 14:04 comment added Martin Sleziak I cannot test this myself - for some reason, the linked question work fine for me. Still I was curious whether people who get the error have access to pages such as timeline or revision history, or whether they'll get the same error there.

Feb 24, 2023 at 20:46 history edited Andrés E. Caicedo CC BY-SA 4.0
Further examples, plus moved an item that was out of order
Feb 24, 2023 at 15:39 history edited Peter LeFanu Lumsdaine CC BY-SA 4.0
made title clearer — original title was cute but uninformative, and such a major bug seems to deserve maximal visibility
Feb 24, 2023 at 12:14 history edited Igor Khavkine CC BY-SA 4.0
added another example
Feb 24, 2023 at 11:41 comment added Vladimir Dotsenko I have been noticing the same, with a number of questions, e.g. mathoverflow.net/questions/71144/…

Added another item to the list
Feb 23, 2023 at 15:55 comment added Steven Landsburg It's happening here, on Chrome from a Windows box: mathoverflow.net/questions/115416/… . Same page gives same problem on Firefox from the same Windows box and on Chrome from my Android phone.

Added another entry to the list
Feb 22, 2023 at 14:23 comment added Jeremy Rickard P.S. I’ve checked OEIS so that you don’t need to.
Feb 22, 2023 at 9:28 comment added Jeremy Rickard There are many, many more instances. If you go to one of the questions already in the list and look for questions with nearby post IDs then you will probably find several. For example, the first question currently in the list is number 8972, and 8974 and 8976 are also examples (8973 and 8975 are not questions). However, it doesn't seem to be a contiguous block of IDs that are affected: 8983 seems fine. Probably we're getting to the point where adding newly found instances to the list is not going to help much.
Feb 22, 2023 at 6:18 comment added Emil Jeřábek Not yet, adding it now. The list of questions is kept updated with all that have been identified; it’s sorted according to the post ID so that it is easy to check whether a given question has already been listed.
Feb 22, 2023 at 6:17 history edited Emil Jeřábek CC BY-SA 4.0
may as well put the original question in, to make the list complete
Feb 22, 2023 at 2:32 comment added Yemon Choi I am not sure if mathoverflow.net/questions/20740/… has already been mentioned

Fixed a typo. Sorry.
Feb 21, 2023 at 15:45 comment added Emil Jeřábek @TimCampion Thank you.

Feb 20, 2023 at 19:20 comment added Dima Pasechnik logging out + clearing cookies + logging back does not help
Feb 20, 2023 at 19:07 comment added Dima Pasechnik yeah, saw these too. :-( time to relocate to a better platform?
Feb 20, 2023 at 17:50 comment added Andrés E. Caicedo Added a few more examples.

Feb 20, 2023 at 5:06 comment added Emil Jeřábek @GerryMyerson Yes, the question in my original report was also bumped to the front page while it was already broken for me, as I mentioned, so the bug only affects some users.
Feb 19, 2023 at 21:18 comment added Gerry Myerson Question 14376, reported here yesterday by @Jeremy, was bumped to the front page five hours ago by an answer posted by another user, mathoverflow.net/users/17261/jjcale?tab=activity – but I'm still getting Kitty. What is going on here?
Feb 19, 2023 at 4:43 comment added Noah Schweber Another one: mathoverflow.net/questions/36580/…
Feb 18, 2023 at 23:31 comment added Sam Hopkins An obvious pattern: it looks like the problem appears only on old (10+ year old) questions, though certainly not every old question has this problem. For example mathoverflow.net/questions/21003/… is broken but mathoverflow.net/questions/54430/… is ok.
Feb 18, 2023 at 22:08 comment added Noah Schweber Two more: mathoverflow.net/questions/121306, mathoverflow.net/questions/10200
