title: git commit nolonger showing up in log
body: <p>Yesterday I git-commited, then checked out multiple old commits and also used <code>stash</code> on some of them. </p>
  
  <p>Now yesterday's commit is no longer showing up in <code>git log</code>. </p>
  
  <p>I dont know the tree-ish but i know the exact comment i used. </p>
  
  <p>I tried checking out the most-recent before yesterday's commit but it still does not show up in the log-tree.</p>
  
  <p>Is there some way to checkout or search by the comment i gave it? (Also is there a reason why it nolonger shows up in <code>git log</code>?)</p>
