If you are using parametric modelling sometimes you run into situations where MS gives you: "One or more constraint has been removed." in the message center.
First of all: It just shows as a small warning in the message center. That is not enough. It is a major thing that MS does to your model. It basically destroys your parametric cell or parts of it. The warning should be more prominent than just a small message in the message center. In the beginning of using parametric modelling I did not even notice this message, until I get used to check for it everytime something seemed off.

But the better thing would be:

Do not delete constraints automatically when MS cannot solve the geometry/ the equations anymore.

What I would like to see if it happens: Show me a pop up: "These constraints are hindering MS from building the geometry with the given values. Do you want to remove these constraints?" Then give me a list or mark the constraints in the view window that will be removed if I click "yes". If users see the constraints which are causing a problem they can improve their design according to their wishes. If the constraints just get deleted, nobody knows which constraints have been deleted, and most of the time it leads to a malfunctioning cell afterwards.
