Can not change some values in the inspector

An example is the mass of a rigid body 2D. I change it in the editor, say from 1 to 10, and when I test it out in runtime, there is no change in how the object behaves. Once in runtime, if I do anything to that object, or change the mass, it will instantly update. It will never start with the mass I typed in the inspector, though.

Another example is the motor on hinge joints. Regardless of the values I set for it, it will not start spinning during runtime until I modify any value in the inspector.

There are no scripts attached to the objects that I am having problems with. I’ve tried messing with the start awake, never sleep etc, moving between normal/debug mode, saving the scene and project, restarting unity and nothing seems to fix the issue.

Any help would be great, thanks.

did u get an answer?
