and two other potentially related things (which bother me, resp., less and not at all, but might be clues):
- when I press "load more" on _top_ of my feed, some very old posts get loaded (when I instead reload the UI, top of my feed actually contains newest posts),
- amusingly, the "@robryk" link in the left pane (see screenshot) opens a 404 page in the right pane (instead of my profile page).

Notably:
1. I did try submitting the post twice, first time I got a toast with "500", so I retried.
2. The post appeared on the target instance after I submitted the self-reply underneath.
