the downstream build graph is ok, the problem is in job builds page where it knows which upstream build initialized this one, but when I go to that upstream build, it shows a list of downstream jobs with no build link ("none" instead).

Also, this causes (I guess) "Downstream build view" to be an empty page.

Similar problem is described here by SauravSengupta:

The jobs we use are mainly free style jobs connected in dependency hierarchy + matrix job (starting on exact time, instead of hierarchy). Hudson ver. 1.353.
