Can't resume my draft.

Saw some people said workaround is to create a copy. Can't do that either.

The draft is from April 4th. My newer drafts from a few days ago work. Is it common that old drafts quit working? Is it possible to recover this draft, or do I lose all the work I put into it?
This is terrible. I miss Turbo Lister very, very much. I also have something to sell that is same as one I sold last year, but I can't copy that auction because it ended over 90-days ago, but I digress. Did I mention how much I miss Turbo Lister?
