Sass sourcemap compiling improperly

The Sass sourcemap in my theme has started pointing me in the wrong source file while inspecting code in Chrome and Firefox.

I’ve tried:

1) Removing everything but the @import statements from the entry files as a workaround for Chrome issues.

2) Recompiling the sourcemap at command line with –sourcemap which I found out was deprecated.

3) Renaming the sourcemap and recompiling. New sourcemap was created, but errors are still included.

I know this is more of a Sass question. Since I’m using Underscores I thought someone here would have an idea.

Any idea what I can do to fix this?
