In OOTP 25, if you clicked "Ask AI to set up development focus", you would get the same sliders every time for the same player assuming the same scouting.
In OOTP 26, the sliders for pitch mix when clicking "Ask AI for plan" are not deterministic. I.e. if you click the button multiple times for the same player, you will get multiple different pitch mix sliders. This is likely unintended.
