Sounds like you're expecting Heat to respond to the stop/delete of one
of the instances in the group.

It doesn't do that.. yet. There's a very large scale effort under way
called 'convergence' that will add such a capability to Heat (by having
Heat try to assert that reality should match intention). Until then it
doesn't support this use case very well.
