The timing of h1lsc0 was glitched during its fan power upgrade. I checked the IO Chassis was seen by the computer and then restarted all the models with /etc/startWorld.sh. 

Despite h1lsc0 being the timing master for h1oaf1, it did not appear that h1oaf1 needed a restart, (and so its models were not restarted).
