RO not being placed on the correct device(s) downstream after upstream breaker is closed

There is a scenario that is causing customer outage data to be reported incorrectly. This is occurring after an upstream device is closed, but it fails to move the RO to the downstream open device(s). It creates a new RO incorrectly on the upstream device which impacts reporting for SADI/SAFI numbers.


STEPS
-----------------------
Scenario:
1.  Identify a bypass loop and operate it to bypass the area.
2.  Open the upstream breaker
3.  Open a switch (or conductor) just downstream of the bypass area
4.  Do not create a nested outage
5.  Close the breaker
Once the breaker is restored it should restore the original event on the breaker and create a second event on the switch with only those affected customers.
Instead the second event is created on the breaker with new affected customer count.

This can lead to greater confusion later in the switching process, when the breaker is opened again.
