@gunnarmorling thank you for sharing the diff, that is strange. My output has some superfluous, non-existent stations in the beginning: ``` 1011=1.0/1.0/1.0, 12=1.0/1.0/1.0, 2011=1.0/1.0/1.0, 3011=1.0/1.0/1.0, 4011=1.0/1.0/1.0, 5011=1.0/1.0/1.0, 6011=1.0/1.0/1.0, 7011=1.0/1.0/1.0, 8011=1.0/1.0/1.0,...

@gunnarmorling may I ask, do you consistently get the same wrong output? I don't want to put more burden on you, but I have not been able to get the...

**Edit:** I was able to reproduce, after configuring the number of executors to be 1, 2, 3, 4, 6, 8, 12, 24, finally at 24 I got the same behavior....

@gunnarmorling figured out the bug, should be fixed now. Thanks once more for your assistance.

@gunnarmorling I think that test failure was actually caused by the same bug, and my fix wasn't complete. Hoping there are no more issues now.
