If you have lost track of a recent commit (perhaps you did a reset), you can generally still get it back.
Run git reflog and look through the output to see if you can find that
commit.
Note the sha value associated with that commit.
Let's say it is 39e85b2. You can peruse the details of that commit with
git show 39e85b2.
From there, the utility belt that is git is at your disposal. For example, you
can cherry-pick the commit or do a rebase.
