Aaron - I was looking at this with Support two weeks ago and what they told you is unfortunately correct.
It looks to me like one of our Server Hardening sweeps tagged this as an issue and the code was changed to only allow the file to be written relative to the User ID folder under the Server Data Directory specified on System Agent Maintenance. Totally negates one of the use cases it was added for which is to write to “Fiery Hot” folders.
I will raise the issue for review.
