Thanks for this @RJ722, looks like our update script needs to account for using a submodule for MathJax. Sorry for the inconvenience.

Hey sorry for the delay here, I will work on this change today.

I've updated the v0.10 builds to all include Mathjax, so this particular issue is resolved now.

We'll continue work on optimizing this on #181.
