Within the last hour or so, I made suggested edits to a question ("Why does greyscale work the way it does?") to fix minor grammar errors. I explained that the edits were minor, but that the question ranked in the first five in the Google results returned for the "grayscale algorithm" search phrase, and therefore I wanted to further improve it.
After submitting my edits, I received the usual "your edits will need to be reviewed" message. But after waiting for more than 10 minutes, my edits simply disappeared upon page refresh. There was no "rejected" notice, or any other notice for that matter.
Why is this? Is this a fluke, or what really happened?
