The reverse is to expected and it's often up to 1000 relays. However, the mismatch in this case is often anywhere from 1 to 100 relays. How to replicate: ``` Code highlighting: {{{#!python serverdescriptors_dict = dict((str(x.fingerprint), x) for x in DescriptorDownloader().get_server_descriptors().run()) consensus_list = [x for x in DescriptorDownloader().get_consensus().run()] mismatch_count = len([x.fingerprint for x in consensus_list if x.fingerprint not in serverdescriptors_dict]) }}} ``` Here are the results from multiple runs: 88 16 91 1 1 86 1 88 90 90 17 Unclear where this bug is, it could be in the TOR protocol itself perhaps.
