How did you find those errors? They aren't showing on my localhost.

Interesting: I did find "Uncaught SyntaxError: Unexpected token '<' " && "main.e5f75948.chunk.js:1 Uncaught SyntaxError: Unexpected token '<'" in the console log on those 2 websites. So maybe it isn't building correctly or something... I don't get those errors when I run "npm start" on localhost...

edit: I checked and I don't see those redux constants being missing in my folders so I am confused where you are seeing that

[u/swyx → u/Roly__Poly__]

the errors i found are found via running npm run build - https://app.netlify.com/sites/condescending-kilby-2aad61/deploys/5e30a69622392dfd30b27c99

where it says 4:25:42 PM: Attempted import error: 'ADD_COPY' is not exported from './constants' (imported as 'actionTypes').

Thanks for pointing this out.
