Swagger editor 'dist' folder missing

[ebergFL]

My Swagger

 # paste your swagger document here

• Swagger Editor version(from Help > About menu): Version 2.10.1
• My browser: Chrome Version 50.0.2661.102 m

Issue
I cloned and installed the latest master from git:

git clone https://github.com/swagger-api/swagger-editor.git
cd swagger-editor
npm install
npm start

The editor came up blank, found missing files and the root folder 'swagger-editor/dist'. Copied 'dist' from another branch and restarted the editor, editor appears to be working.
