Heroku believes that everything is relevant when it is not

I recently did:

git push -f heroku master

      

        
        
        
      

    

Now when I try to push new changes to the hero, it says, "Everything is up to date." Maybe forcing the latest git push has nothing to do with the problem, but I'm new to Heroku and git and I'm completely lost.

Also, I am working on the "master" branch:

git branch
* master

      

        
        
        
      

    

I don't even know what to try. Any help would be appreciated.

EDIT:

Maybe this helps: when I click on Github it also returns "Everything updated". But the difference is that Github does have the latest code. Heroku, on the other hand, doesn't have the latest code. I am sure for this reason, I can easily compare the css file that is hosted on Buzz Amazon (heroku), the css file on Github, and the css file on my local env. Github and my local envs are identical, and the css file on github doesn't reflect the changes. ... Maybe this is a collectstatic issue ?.

UPDATE:

This is a collectstatic issue, I haven't solved it yet. So, if anyone has a similar situation, consider double checking your Amazon AWS S3 - Django configuration. GL.
