Failed to load config.yml (404)

[sitefinitysteve]

Describe the bug
On localhost I can get to /admin and see the netlifycms login, the network inspector shows it getting the config.yml from /admin/config.yml

When I deploy to Netlify though it seems that it's trying to load it from /config.yml.

If I hit it at the proper /admin/config.yml on live, it's clearly there, why it's being served from root I have no idea.

To Reproduce

Expected behavior
NetlifyCms admin login page

Ok, so... it works now. I disabled the netlify asset optimization (of which I only had images checked... was causing janky images though so I disabled it)

I dunno!?
