I've asked a similar question before: Why are there no review tasks generated for a couple of my recent First Posts on a site? but that has been fixed. Yesterday, I posted my first answer on a site but again it didn't get reviewed. Did the bug regress, or was this answer skipped because I was over a certain reputation threshold already (due to repairing broken images)? I've written a SEDE query to list the review items of that day; looking at timestamps, it could have been the task with ID 318365, but that got deleted (or not created at all) somehow.
I checked my deleted answers and questions on that site already, but there were none.
