The magically disappearing blog posts

Blogger and I are having issues. Sometimes, while scrolling back through old posts, I'll realize that some posts are missing. For example, when going from Page 1 (last post: Oct 21) to Page 2 (first post: Oct 6), I realize that all the posts from between those dates (Greg and Katherine's wedding, Bailey's birthday, etc) are missing.

Yet when I do a search for "Bailey + Birthday", that post appears at the top. 

Strange, no? I'm not sure what's going on.

Update: And now they have magically reappeared. Weird.
