CSS rules no longer updating

After moving around multiple CSS files between the client and public directories, I’ve now landed myself in a situation where nothing is getting updated, even though main.css is now where it was originally (in the client directory). For example, the background of my container element still remains colored despite deleting that rule. I’m using Chrome in incognito mode, so it has nothing to do with the browser cache.

Updating Meteor from 1.7 to 1.8 did not resolve the issue. In addition, I’ve tried deleting the .meteor/local/bundler-cache directory and then rebuilding, but to no avail.

Any suggestions would be most appreciated. It would also be good to know the standard modern way to structure multiple stylesheets.
