Facet.instances not resolving correctly if facet is stated multiple times

[temujin9]

cluster :broken do
  facet(:collector).cloud(:ec2).security_group('broken-collector').authorize_group('systemwide')
  facet :collector do
    instances           2
    cloud(:ec2).flavor        'm1.large'
  end
end

It appears that facet.instances is getting set to 1 by the first facet statement (as a default), which is then swamping out the later instances during resolve.
