Uncaught TypeError: t.shuffleCustom

Hi,
I’m experiencing an unusual bug where I occasionally get a javascript error on the page that prevents the page from displaying the feed. The data is there and hidden however, it will not display given javascript fails before the function to do so I’m assuming.

The error received is:
Uncaught TypeError: t.shuffleCustom is not a function at b (public.js:1)

Strange part is, it doesn’t always fail – it sometimes works without the error occurring.
This would assume a runtime error (ie something that is meant to load before this script, isn’t).

Has anyone experienced this as its rather annoying.
