Thanks, that worked.

One thing I noticed that I wasn't sure about is that I SSH'd into the
server and ran git update-ref to restore the tag. That created the
symbolic name in .git/refs/tags/NAME to point to that tag object. But
what I noticed is that the only file listed in .git/refs/tags is the
tag I restored. There are other tags in the repository (and a fresh
clone gets them), but they don't show up in that directory. Is it
going to be a problem that ran git update-ref on the server (which is
a bare repository) rather than on a clone that I push? I just want to
make sure that the tag objects are referenced so they don't go away
after the 2 week garbage collection grace period.
