RPA Process Status of "ABORTED-ORPHANED"

Hello everyone,

I can't find a single mention in the docs for this, so here I am - does anyone know what 'Orphaned' means for the result of an Appian RPA process? The process was a longer running one (looping over several pages to pull data out) In the Robotic Processes tab of the Appian RPA dashboard, the Result shows as Aborted and Orphaned. It shows pretty much the same thing in the Monitoring -> Events tab.

There's no error in the process indicating why it would have broke, so any insight is appreciated!
