2K did mention that they were able to tune the gameplay remotely through non-patch updates this year. That's actually a good thing in theory, even though it messes with your carefully crafted sliders. There's a chance it might actually be improving the stock gameplay, however, which might cause your sliders to over compensate.
Anyway, I've been having great games with your sliders. Even had a loss that I didn't mind so much (because the screwup was on me after an incredible comeback).
