When modify "shared object of Reference id" to manage VPM of object name.
After modify reference id, the error "Object "XXXXXX" has been removed but it is still referenced...." display when save policy by ManagementCenter of VPM editor.
So I can not install this policy by this reference error.
"Object "XXXXXX" has been removed but it is still referenced. The rule referencing this object must be removed"
That error message means reference id miss mach has occurred.
Need to modify all related reference id if you modified reference id by ManagementCenter of VPM editor.
Please use VPM editor of "Object Occurrences" function.
You can easy to find where use related object.
