title: Most of my assets suddenly return 404 after a push to heroku
body: <p>I have deployed this app (rails 3.2.11) a million times, I haven't messed with any settings, but now I'm greeted with this:</p>

  <p>Why did this happen out of the blue? My conents of application.rb include <code>config.assets.enabled = true</code> - never had any issues.</p>
  
  <p><strong>In fact running it locally on port 3000 seems to not have any issues whatsoever.</strong></p>
  
  <p>After deploying to heroku this morning, it seems that it loads nothing that's inside /assets/</p>
  
  <p>Interestingly, after copying the files over to try and just make a new app, <code>git commit</code> results in all the stuff you'd expect as well as a LONG list of these which I think might be related:</p>

  <p>Edit: Interestingly enough SOME of the assets have loaded, like the logo and the background, but the rest as you can see return 404.</p>
