I have simply updated my main.css file locally, committed it to github and my changes are not showing. I have confirmed these changes should in fact be working by editing the same file with the same small style change in Chrome's developer console. I have checked my github repo and it has all my code up to date. I even made a small HTML change in the same commit and that change was made in the live heroku app. I have tried clearing all heroku/github and chrome caches to make sure that an old CSS file wasn't being used but this is not the case.
Why won't the CSS load? Is this a Heroku problem?
