[ I was told to send this to tor-commits but I seem to be unable to send email there. ]
In order to remove some inconveniently large and also potentially copyright-infringing files from the revision history, https://gitweb.torproject.org/stegotorus.git has been rebased. If you pulled from that repository, you're going to need to do a forcible branch update or a re-clone. (I am under the impression that mostly nobody did that because they were waiting for me to do this.)
