Unfortunately I had a long-standing latent bug in my configuration file that triggered on a (persistent on-disk) edge case which would cause the shepherd process to enter an infinite loop (because the shepherd configuration language is Turing-complete enough to allow infinite loops in the first place). All the remaining generations (since I didn't like keeping more than a dozen, and had recently been excessively tweaking the configuration file) had this bug, so I had no way of reverting to an even older generation that predated the bug.
Thanks
