I'm not an expert on this, but is it possible that `lnum` and `tnum` features are missing? This is a problem for applications relying on them (I stumbled over it by trying the fonts with `lualatex` and the `fontspec` package). The figure versions themselves [are there](https://github.com/adobe-fonts/source-sans/files/7626011/xtest-crop.pdf).
