Disappearing Unpublished Projects.
I just came back to do a bit more on it, and it's gone. No sign of it in my unpublished list.
A quick glance through my unpublished list, I see that at least two other unpublished projects without images that I made a brief start on in the last week or two have also disappeared.
Personally, I haven't lost much, they were just notes to remind me to actually do the projects, but it could just as easily have been a huge ible I lost.
That makes it an important bug that needs fixing before too many people lose too much work.
