Web preview caching issue?

My preview in the web browser used to update immediately upon making changes to my SCSS file (opened in Sublime). At some point in this project it changed: When I make a change and save, the browser refreshes, the BSS preview updates but the refreshed browser view doesn't render the update...almost like it's stuck caching the old CSS. Seems strange that it worked fine before... Any ideas?

I had something similar happen last night when working on a javascipt file opened in Sublime. I saved in Sublime and it was not updating the code changes. I went to work on some html stuff and previewed and that is when the code changes I made in the javascript file showed up (which had a mistake).
