Reason for Plan Change

(why-valid 'a-36)
A-36 [Call-WS DHL-Shipping PENULTIMATE]
is VALID and supported by decision FIND-COMPLEX-WEBSERVICES-15

* (why-optimal 'FIND-COMPLEX-WEBSERVICES-15)
Decision FIND-COMPLEX-WEBSERVICES-15 is to reduce goal PENULTIMATE,
and is preferred to decision FIND-COMPLEX-WEBSERVICES-2
because:
Decision FIND-COMPLEX-WEBSERVICES-2 is not valid.
Decision FIND-COMPLEX-WEBSERVICES-2 applies to goal PENULTIMATE
But it is no longer valid because:
the fact [failure HPN-Shipping] is believed.
