I fixed the issue. I for some reason placed the ID as the parfile. However, starting the simulation segment ends short when the thorn Kadath_Importer cannot be found. The parfile I am using includes it as an active thorn and the thornlists seemed to have included in both KadathImporter and KadathThorn. KadathThorn also fails to be found when included in the parfile.

I have included both the output and parfile below for a BBH setup:
