huey: task not found in TaskRegistry

I just upgraded to the latest version in master to make use of the fix for closing the db but it seems huey is no longer finding the tasks after the update for some reason. I was already running a pretty recent version so not sure what could have changed… i upgraded huey and restarted the workers which should recreate the task registry in redis again right?

QueueException: queuecmd_create_initial_notifications not found in TaskRegistry
  File "huey/bin/huey_consumer.py", line 124, in check_message
    task = self.huey.dequeue()
  File "huey/api.py", line 211, in dequeue
    return registry.get_task_for_message(message)
  File "huey/registry.py", line 70, in get_task_for_message
    klass = self.get_task_class(klass_str)
  File "huey/registry.py", line 60, in get_task_class
    raise QueueException('%s not found in TaskRegistry' % klass_str)
