Celery is not loading tasks from one app out of five

Question

I'm using autodiscover in my celery.py file for gathering tasks. Which up until a recently picked all of the app.tasks.py up, I'm not sure why but my config.tasks.py function are no longer being picked up, but all the other apps are. If I from "config.tasks import *" there are no errors and I can run the tasks manually through shell.

ive tried using force=True on autodiscover which had no effect, and a number of other solutions, none of which seem to have any effect, does anyone have any ideas on what to check next?

Thanks

Have you got an __init__.py file in the config folder?
