Alright, the results are in, and there in fact IS a bias to the left, on my machine at least. I've set up a test mission, and my conclusion is that ~2/3 mines will land to the left, rather than the expected ~1/2 mines.

Alright, thanks for your effort. I'll check it out on my end later, and see if I can still reproduce it.

Strange, I tested it locally on the editor, and in numerous tests they always went left. Is it possible that it keeps using the same seed (Edit: in the same session), resulting in the same pattern?

Issue can no longer be reproduced after switching back and forth between main branch and dev branch (now version 1.69.140502).

I can no longer reproduce this issue in 1.63.137310.
