This has happened twice now, on two separate SE sites: I type an answer, click "Submit", and when the page refreshes, my answer isn't there. The answer does get submitted, and does appear the next time I refresh the page, but it still leads to a brief moment of panic that it might not have been submitted and I'll be forced to type it out all over again.
Indeed, when I submitted this very Meta question, it took me to a 404 page, and I had to refresh to get to the actual submitted question. So questions are being affected as well.
Has anyone else experienced this issue, and can it be looked into?
