I have a super simple test DAG that looks like this:

Hi Aaron,
It looks like you hit a bug:
https://issues.apache.org/jira/browse/AIRFLOW-1977
Currently I don't have a solution for this at hand, I have to dig into the
code. If the DAG is scheduled one, you might want to try setting it to None
instead of @once: https://airflow.apache.org/scheduler.h
