Upgrade to Unity 5 Physics: Weird multi collision force amplification

    I recently upgraded an old pre-alpha prototype I've had (so please excuse the graphics) to Unity 5. I'm seeing a force amplification when an object collides with more than one object simultaneously. In the video below it's the 5th basketball shot but I see it continuously ONLY when the basketball hits the backboard and the rim at the same time (the first four shots are more typical normal physics behavior. The video and inpector of the physics material is below (rim is attached but ball and backboard are same just with different bounciness and friction values). Any ideas? Has anyone else seen this in Unity 5 when you collide with multiple objects at the same time?
