Comment (by cypherpunks):

 > Okay. A consensus arrives

 Your case happens if consensus were set by
 networkstatus_note_certs_arrived(), it miss all update_*() functions.

 Alas, it's not last edge case that trigger thus warnings.
 nodelist_set_consensus() must to clear all node->md like it does for
 node->rs to fix all remain cases.
