666!!!!!! I win

Is there a word for it?…. To describe that process when a change to a rule or law is called for and introduced, to address a problem and succeeds in creating an unforeseen and a possibly bigger one?

I am thinking of things like the guest prefix and rule changes in sport. A good example is the offside law in football. It was introduced to prevent the ball being lobbed on to the head of a forward. It was thought that this would improve the game. It has ended up being used as a defensive ploy and now very much to the detriment of the game.

I am reluctant to criticise the guest prefix too much, because Max was really responding to our calls that he do something. It did indeed solve one problem but has left a very confusing legacy.
