test_rigid_object.py seems to be failing, could you check if it's passing locally?

Should we throw a warning about this finding from the code? This way users know that if they see some issues in forces, they have a heads up?

Suggested change

	Setting this flag to True should only be done if the simulation steps are very large (less than 30Hz).
	We recommend setting this flag to true only when the simulation step size is large (i.e., less than 30 Hz or more than 0.0333 seconds).

[Mayankm96]

This should be a warning. Also a bit confusing: are forces just computed incorrectly or they are reported wrong?

Suggested change

	Enabling this flag can lead to incorrect forces being read from the contact sensor.
	.. warn::
	Enabling this flag may lead to incorrect contact forces report from the contact sensor.
