Ember loading substate not working from addon

I have an Ember addon that is npm linked with a project.

If I create the file app/pods/application-loading/template.hbs in the addon, the loading HTML is not rendered from the base-project. However, if I create the exact same file in the base-project itself, the loading HTML is rendered.

My understanding is that the addon’s app folder should be merged with the base-application’s app folder, so this shouldn’t be possible. What’s going on?

You may be running into snags between pods and non-pods with the loading state. Loading states work differently in pods than normally, but that looks like the right spot off the top of my head. If you put it in the “classic” spot does your loading state show up?
