Disappearing new post (iOS)

I wrote up a nice little link post on /3DS and posted it. It seemed to go through fine, and even showed up afterwards...

I went to fix the image on my laptop (the ability to select/change a preview image didn't seem to be there on iOS) and the past wasn't there...

So I refreshed on my phone, and it was gone. Is it possible I put it in some sort of draft post purgatory?
