Restarting a sheriff with the same config removes commands

[heuristicus]

Running on the anymal with each machine running two deputies, one for the default configuration and one for subt, starting

~/robots/drs/subt_ws/src/darpa_subt/anymal/anymal_coyote_subt/anymal_coyote_subt/config/procman $ rosrun procman_ros sheriff coyote_subt.pmd

Loads as normal (except both jetson deputies seem to appear?).

Killing this command and then running it again results in many of the commands being missing, and output in the terminal of

Traceback (most recent call last):

This does not seem to happen consistently and the commands that are removed are not always the same.
