Ok so I've added the listeners and I have run 2 scenarios:
1. I do not recreate the KA before I re-run a session, and all the info that
I get even after having deleted a rule from the package is :
// at the beginning

2. I re-create the KA before I run a session, and dispose of the previous
KA, and this is what I get without even making any changes to the rules (the
same messages stating that the services have started are present but not
included):
// after disposing of agent

>From what I'm reading it seems that the Guvnor resource package is null and
so there is nothing to subscribe to. I do not understand what I might be
doing wrong in this case or how to fix this since the rules are actually
included in the knowledge base.
Thank you very much for any help!
