Can anyone else verify any problems with the physics engine since the 6.11.4 update?

I have a vehicle that has 4 wheel constraints and two hinge constraints. Since the last update the wheels, axles, and chassis are all colliding with one another. If I set all parts to be passable except the wheels it works fine.

It seems like such an obvious problem it should be easily verified.

I try just adding one wheel to one axle with one wheel constraint. However, if the axle is not passable the wheel starts to collide with it when motored.

All the objects are in the same group.
