File Watcher not triggering for scss

I have a project that I am working on and the SCSS file watcher just stopped working randomly. I have a different project and it works just fine on that one, but I can't get it working again in my current project. The file watcher settings are the same on both projects (exported and imported). Has anyone every come across this? Using the newest version (as of this post) - 2017.3.2.

File watcher settings:

Program: C:\Ruby24-x64\bin\scss.bat

Arguments: --no-cache --update $FileName$:$FileNameWithoutExtension$.css

Output...: $FileNameWithoutExtension$.css

Working Directory: $FileDir$

Like I said, these settings work just fine on one project, but not a different. I'm also not getting any errors that I can see. Any thoughts would be greatly appreciated.
