Sorry, I didn't see this reply before.
The download issue is resolved in the 8.4.1 beta; however, I had some other jobs that stopped working correctly due to what appeared to be an inability to use job variables of one job in the tasks of another job (which had previously worked). I did not have time to investigate more thoroughly due to a major deadline coming up this month, so I ended up just copying the job variables to the dependent job and moving on. The comment I made here was meant to imply that if I couldn't identify that issue has having somehow arisen from something I did, I would report it as a separate problem. I haven't had time to do that, either, though.
