 Sometimes file `cached-microdesc-consensus` contains duplicates of some
 Tor nodes which differ only by keys. For example, today (Mon Dec 10
 17:17:29 UTC 2018) I saw these duplicates:

 Is it a bug? Now
 [[https://metrics.torproject.org/rs.html#details/28353A8C2453ADBD8EE0147130C45D9C67A054D7|this
 node]] is out of consensus.
