I noticed hReview snippets stopped showing for LOCAL results about a month ago. I had DOUBLE organic + Places stars for a lot of clients, which was cool while it lasted.
Then hReview in regular organic started to disappear about a month ago. Everyone in my market below my #1 spot lost their stars. But it's weird mine still show most of the time. BUT they come and go some days. I'd say they are up maybe 70% of the time.
So bug or clean up due to too much rich snippet spam? Just not sure.
