Upon reloading configuration from disk, with no jobs running, any free-style
jobs that have upstream/downstream relationships lose those connections. After
reload, execution of a parent job will not kick off the children jobs. When
looking at the parent job's and/or the children jobs' overview pages, the
upstream/downstream connections are not listed. However, if you go to the
configuration page for any of these jobs, the connections are indeed listed.
The only way to functionally restore these connections is to click "Save" on ANY
of the job configuration pages. This restores the links for all connected
free-style jobs.
