asHtml() breaks when document contains list-item in content

I found a bug today in the fragments parser when attempting to use asHtml() to render my page today. Removing the bullet points in the Prismic.io editor fixed the problem, so it appears to be specific to list-items.

My api with post in question is: 
https://mobicorp.prismic.io/api/documents/search?ref=U21dGAEAADEAo8sa&q=%5B%5B%3Ad+%3D+at(document.id%2C+%22U2ucHgEAAC4ALRo1%22)+%5D%5D

The error printed in my terminal:
/Users/jmelvin/Development/mobicorpcom/node_modules/prismic.io/dist/prismic.io.js:1380 
blockGroup.blocks.push(block); 
^ 
TypeError: Cannot read property 'blocks' of undefined
