I think it's *extremely* unlikely that fsck was involved, because
it just doesn't do things like that.  It might move an orphaned
directory (or file) to lost+found, but nowhere else.  That's in
addition to the fact that, as someone already mentioned, it asks
before doing anything.  I don't know enough about the details of
journal recovery to comment on it as a suspect.

Any chance that your base system -- rather than one of the jails --
has somehow been cracked; maybe even that the cracker precipitated
the crash?  It might be wise to restore the whole system from backup,
the base from a moderately old one since it doesn't change anyway,
rather than trying to recover.
