Severity: 3Workaround is possible

The issue happens only when the rigidbody has Freeze Rotation on the Z axis set to true and the parent object of Particle System object is moved. If the Particle System itself is moved, everything works as expected.

To reproduce:

1. Open the project, attached by the user (New Unity Project.zip)
2. Open the "Scene1" scene
3. Enter Play mode
4. Move the cube with A and D, and then stop
5. Observe how particles are still being emitted

Expected: the Particle System doesn't emit when the object is not moving
