I am using this in a medium large React project as part of the Webpack flow. For compression we are using the Babili-Webpack-Plugin. As this is just a small wrapper around Babili I figure the following issue is more related to Babili itself:

These are the relevant software versions:

• Mac OS Sierra
• Node 6.9.2
• Babili Preset 0.0.9
• Babel Core 6.18.2
• Babel Traverse 6.19.0

Is there anything I can do to debug this anymore?
