Inconsistent output

[QazCetelic]

I was looking to test the performance impact of several parts of the program and was setting up some tests to ensure I didn't break anything while testing. However, I had some issues setting up my test for validation purposes, the output kept failing the comparison with the validation output.
I then checked the SHA-256 hash of the output and again after running it once more and the hashes differed. Here are the results calculated with sha256sum:

Is this intended? I can't think of a reason, since the results should be the same and the order of the parallel execution shouldn't matter due to the alphabetical ordering of the stations but I'm probably missing something 😄.

It seems that it sometimes outputs the values for a station twice.

(I've replaced all ocurrances of , with \n because the diff checker doesn't work on 1 enourmous line)
