Corruption in blogger database producing lost posts?

This is a bad bug. I created a post in Blogger yesterday that has vanished. It's still on blogspot
but it's not accessible in Blogger. If I click on the edit link that appears (when authenticated) below viewed blogspot files I get this error message:

The post you were looking for was not found.

From the error message I can see the blog and postid for blogger:
blogID=5710205
postID=113090838306544429

The only way I can see this kind of asynchrony is if there's a corruption problem in the blogger database. Not good.

I only discovered this because I had a link to the now lost posting in another blogger post that still exists. I wonder how long this has been going on.
