can't use compass in compass project

I've create a compass project in VS2015 and it works fine until I try to use a compass mixin in which case it can't find it. I figured the problem was that i needed to import compass, but when I do that several things occur I get this error added to my css file:

Errno::ENOENT: No such file or directory - C:/Users/abailey/Source/Workspaces/Jbs.Cedb/Main/Source/Jbs.Cedb/.sass-cache/75fcaf1b4852ceb732871195e41567cc2a7d8997/C%058/Users/abailey/AppData/Local/Temp/Mindscape/WebWorkbench/Ruby193/Ruby193/lib/ruby/gems/1.9.1/gems/compass-core-1.0.1/stylesheets

I do see this message still whenever I compile, but I don't see any other files that need to be included in the project:

Web Workbench created output files in the following directories which are not part of the project:
* C:\Users\abailey\Source\Workspaces\Jbs.Cedb\Main\Source\Jbs.Cedb\Presentation.Mvc4
Please include these folders to the project using Show Hidden Files and Include In Project.

I don't see any .sass-cache directory created (and I can see hidden files).

Thoughts?

I decided to compile outside of VS and still got the same error, after some googling I learned it has to do with the sass-cache path being longer than 255 characters. By editing my config.rb file to set the path somewhere closer to the root of my drive I was able to get rid of the errors.

Example: cache_path = 'C:\temp\sass\'
