Website currently crashes with redux errors

Tried visiting the production arrows.app and get a blank screen with this in the console:

```
Uncaught Error: Minified Redux error #0; visit https://redux.js.org/Errors?code=0 for the full message or use the non-minified dev environment for full errors.
