Hi, Vaclav.
In certain circumstance it would break simulation.
For example, when a sphere is moved from one side corner to the other side.
See attached file. So, please, keep it optional if it need.

ps/ In my opinion, if the overlap is more than the radius, it said too low stiffness and an error in the physical model... Or is there another reasons?
