You sent me this: "1. Please ensure that you refer to Supplementary
Data (Rhea Cartilage Data and Turkey Necks) in your text as, if
accepted, production will need this reference to link the reader to
the Data."

However, when I went to make upload the tiny change to the manuscript
file (Action Links -> Edit Revision -> Attach Files), I found that the
revision claims to have the old, initial manuscript, that it lacks the
change-tracked manuscript and the response to reviewers, and that it
has discarded figures 2, 3, 4, 5, 7, 9 and both supplementary files.

What the heck is going on? I know that the revision as I submitted
correctly included the right versions of all files, as I viewed it in
the submission-proof PDF.

Here are the changes actually required: perhaps you could make them to
the revised manuscript yourself?
1. At the end of the Table 1 caption, add: "Also available as SI 1"
2. At the end of the Table 3 caption, add: "Also available as SI 2"
