Ok, a bit confusing but I'm curious if this is just me, or if it's a bug.
I have some posts in draft status. I edited the Post dates to be in the next day or so, then continued to work on them. I save pretty religiously using Ctrl-S, and did so repeatedly. I saw the usual confirmation at the bottom of the post window - "Saving Draft..." then "Draft saved at <time>". So far so good.
Then I left the page, did something else, and came back. Most of my post was missing. It turns out that everything it claimed to have saved via Ctrl-S was lost.
Testing has shown that if I click on the "Save Draft" button, changes are successfully saved, but if I use Ctrl-S, they are lost - despite the message saying the draft was saved. In Revisions, I only have drafts saved via the button, never via Ctrl-S.
I have never had this trouble before, and if I remove the future date, Ctrl-S saves fine again. It sounds awfully like this is to do with having a future date for the post.
Any thoughts? Thanks!
