Hi Brian,
I turned off all plugins, and then reenabled them one at a time. No change. As soon as I changed themes, it worked fine. So what I did was enabled my theme again, and started to add files back into my theme one at a time.
It seems the conflict comes with my custom overrides for the default woocommerce emails. Is this a bug, or did I override the emails incorrectly?
Below is a .zip of my /woocommerce/ directory inside my theme.

I am curious if this is an issue with the plugins, or on my end.
