Was the store upgraded from a previous version of neo4j? Sorry, without the store I can't diagnose what went wrong. The method of copying over the healthy data to a new store is, I believe, the best way to go about it. Fact is that these problems should never occur normally, and every known occasion often results in some kind of bug fix to improve neo4j to not produce the same inconsistency again.
I hope you can recover and continue.
