To be honest, I don't understand clearly:
(1) How did you get the issue?
(2) Did you create snapshots after crash?
(3) Had you some snapshots before crash?

If you had a crash then you should have some error messages in the
system log. Have you something? Or did you lose all error messages
during the crash?

Anyway, I need to have the reproducing path for investigate the issue.
Of course, I am not going to wait 160 days before achieving the issue
reproducibility. :) One of the possible way is to share some small
NILFS2 volume with good issue reproducibility. But, currently, I don't
quite follow in what way I can reproduce the issue.

Thanks,
Vyacheslav Dubeyko.
