Did they change the physics on this update?

Maybe not on all cars, but I know with my Jesko, I had it all tuned and dialed in and it drove phenomenally before. All of a sudden it drives like it did before I put hours and hours into tuning it. Slides everywhere, can’t put power down, and understeers or oversteers like crazy. Again, I had that all smoothed out really well with my tuning, but not only does the car feel different, it seems like tuning properties are different? The braking and accel figures are also different from where they were before patch (either the braking/accel calculation properties are now different or my tunes changed without me changing them, which seems odd considering I saved and downloaded them to be sure).

Anyone notice this?
