title: Files disappeared from repository, but there is no deletion in commit history
body: <p>I have a bit of a puzzle at my hands: several previously-committed files disappeared over night, but there is not a single commit that shows they were deleted. How could that happen?</p>
  
  <p>The situation is as follows:</p>
  
  <ul>
  <li>I have a private Git repository on BitBucket, with a single branch.</li>
  <li>There are 3 other people in my team, and everyone is using SourceTree as their git interface.</li>
  <li>Yesterday I pushed a commit - and after it the repository was okay.</li>
  <li>Since then all 3 other team members pushed several commits:
  
  <ul>
  <li>one was a local merge,</li>
  <li>two were online (ie. through-a-webpage) <code>README.md</code> edits,</li>
  <li>one was online (ie. through-a-webpage) deletion of a single unrelated file,</li>
  <li>and the others were several commits with 1 or 2 files.</li>
  </ul></li>
  <li>In the morning, I pulled the repository, only to find several different files, which were committed by different people at different times, were gone from the repository:
  
  <ul>
  <li>they are gone from the local copy,</li>
  <li>they are gone from the <em>Source</em> page on project's BitBucket website,</li>
  <li>they are gone from the .zip downloaded from the <em>Downloads</em> page.</li>
  </ul></li>
  <li>However:
  
  <ul>
  <li>none of the commits after mine delete any of these files,</li>
  <li>I can go to an earlier commit that modified one the "disappeared" files, go to its summary page, view its history - and none of the commits in it deletes the file either.</li>
  </ul></li>
  <li>I double checked that nobody messed with <code>.gitignore</code>, but it was untouched since last December.</li>
  </ul>
  
  <p>Also, as to further confuse the issue: several months ago I added files <code>A.R</code> and <code>test-A.R</code> in a single commit. Later I renamed the <code>test-A.R</code> to <code>test.A.R</code>. Now <code>A.R</code> is still in the repository, but neither <code>test-A.R</code> nor <code>test.A.R</code> is still there.</p>
  
  <p>So, what could possibly cause the files to be deleted from Git repository <em>without</em> any of the commits actually deleting them?</p>

  <p>PS. Of course, I filed a support ticket to BitBucket Support, but I'm not terribly confident they'll respond quickly.</p>
