rails activeadmin redirect loop
===

I'm using activeadmin along with a separate devise user model.

Here's the top of my routes.rb

    devise_for :users

    devise_for :admin_users, ActiveAdmin::Devise.config
    ActiveAdmin.routes(self)

I'm getting a redirect loop  when logging in as an Admin under the activeadmin interface.
Everything is fine for normal users.

If I change the activeadmin route to...

    devise_for :users

    devise_for :admin_users
    ActiveAdmin.routes(self)

everything works but it uses the normal devise sign_in form instead of activeadmin's form.

I checked out [this][1] question but that didn't help.

I'm not even sure where to look as I'm not overriding the activeadmin devise controller.

This was working yesterday but I can't figure out how I broke it.
