"table not found" under admin routing?

Under standard routing, all my actions work as expected, but when I try to use admin routing, suddenly I get “Base table or view not found - Could this be caused by using Auto-Tables?”

If it works correctly without the admin routing, then the error must be wrong. The model is perfectly fine, no? Is this a bug or is there something “more” to setting up admin routing I’m missing?

I think I figured out the problem. The controller code I’m working with is migrated and in the admin actions, it still referenced the model in the singular form while in the non-admin actions it was already migrated.

Sorry for the fire drill.
