At $DAYJOB, a few people have reported "warning: unable to find all commit-graph files" warnings. Their commit-graph-chain files have a few lines, but they only have one commit graph file with very few commits. I suspected something happening during fetch, because (as far as I know) a fetch may cause an incremental commit graph to be written, but I ran a fetch on a large repository myself and didn't run into this problem. Has anyone ran into this problem before, and know how to reproduce?
