I was updating code someone else wrote a few years ago, and they had set [Not ProcedureBlock] on the class. I'm not sure why.

Thank you, Julius! It was that, and my class wasn't ProcedureBlock.

We've seen this behavior too. Whenever we use Job, we see a license used by the user at their computer's IP address, and we also see the job running as their username@127.0.0.1 because it's executing on the server.
