Let’s say that you dream of releasing a history book. That it is not an easy job, and there are strict guidelines you must follow. For starters, you cannot change the chronological order of the events. You also must make it easy to read and to understand for others. 

You might know that feeling when you are talking with your colleague and discussing a technical problem in your project, and he says that everything is working fine on their computer. Not the greatest feeling, right?

I hope you try to understand why it is happening instead of pushing the changes to the server and testing it there.
