Site won't refresh correctly with template using pug files

I'm currenly using the Stun hexo template ([hexo-theme-stun-master](https://github.com/liuyib/hexo-theme-stun)). This template uses pug files for coding all the templating elements. Each time a pug file or file being referenced by a pug file is changed, BrowserSync runs a refresh, but nothing really changes.

A hexo server full restart is required for the pages to render correctly.
