Strange phenomenon, am I alone?

There is server-side caching and local caching - I doubt you are experience server-side caching issues as you would have had to enable that caching your self. You would know that is what is causing the issue.

But, your browser may be storing a copy of the fully rendered page for an abnormally wrong time. Every browser is different, so I would suggest Googling "[your browser] cache" to learn how to clear it and change the settings so it's not caching information for such a long period of time.
