The Case of the Disappearing Post

I seldom add to this blog as the dates on my posts show.  But I never have deleted a post until today when I found that some time since the new formatting Google put into place, some of my blog posts have disappeared and in one instance, only half disappeared but was saved as a draft.  I am not responsible for this so I imagine it is due to the automatic format change.  So I simply deleted the partial post and then deleted two others that made no sense without the posts that had disappeared.  I have not had time to go through all my posts to see what condition they are in.  This reminds me of FB.  There my posts often disappear and then some reappear, even multiple times!   Good old Google.
