Worked: (optional)

Short description of error
If I mixed the rigid body constraints and wind forces in same scene then I got this error in several time. The error is that. When I play the animation (physics simulation) then not moving the rigid bodies. (No animation) And when I delete a wind force then the animation working fine. I can reproduce this but I have no idea which are the exactly situations what is causing it.

Exact steps for others to reproduce the error
I attached a video instead of blend.
Reproduce steps 0.00 to 04:00
You can see the effect from 04:00

Push the space bar and timeline working well but nothing move in the scene.
Delete a wind force and push the space bar again and the timeline working and the rigid bodies moving right.
