OK, thanks for that followup.  I wonder if there's something

Erm, yeah, I just meant if it was in a pack somewhere, not a
loose object.

Did you have any crashes or failed fast-import processes?

OK, so everything works for now and I guess it's not easily
reproducible anymore?

Did the gc+prune expire commit 817390f628f74a55c627f1ddab8a44aa029753a0 ?

I'm also wondering if you used the new public-inbox-edit or
public-inbox-purge.

In the future, it would also be good to note the git version
in use and also to Cc: git@vger.kernel.org
