In current Git master, the `update_certificate_downloads` function in src/or/networkstatus.c contains the following code: ``` if (current_ns_consensus) authority_certs_fetch_missing(current_ns_consensus, now); if (current_ns_consensus) authority_certs_fetch_missing(current_md_consensus, now); ``` The second `if` statement should test `current_md_consensus`, not `current_ns_consensus`.
