[rules-users] unable to update the changes (guvnor rules) to application using changeset

[Esteban Aliverti]

Which version of Guvnor/Drools are you using? There was a known bug that
affected even 5.3 where knowledge packages in Guvnor were marked as
removed: https://issues.jboss.org/browse/GUVNOR-1699
This issue should be solved now.

Best Regards,
