Upgraded from v2.81 to v2.85, physics is now different!

Hi,
I recently upgraded to v2.8.5 from GitHub. I was using v2.8.1 before. My simulation now does not work the same as it did.
My simulation is a sphere on a large flat box. A small force is applied to the sphere. The sphere should move.
In v2.8.1, the sphere moves along the box's surface then comes to rest gradually.
In v2.8.5, the sphere comes to an abrupt stop.
Sphere Physics Values:
Mass= 1 / Friction=1 / Restitution=1 / Gravity=120 / Linear Dampening=0.6 / Angular Dampening=0.6
Box Physics Values:
Friction=1 / Restitution=0.5 / Gravity=10
Things i have tried.
I have used WinMerge to check that its not any recent changes to my own code.
I have also tried my simulation with v2.8.1 again to check if it works as expected. It does(meaning the ball comes to rest gradually).
So my question is, do i need to recalibrate my simulation for each version of bullet?
Or is there another issue that could be causing this, unrelated to the version of bullet i choose to use?
