Compiling blueprints with a reroute node attached to a class variable to a "Spawn for gameplay task" causes the pin to "instigator" to disconnect

Creating a reroute node between a class variable and a "Spawn actor for gameplay task's" class pin will cause the variable attached to the instigator pin to disconnect.

1. Open attached project
2. Open the MyActor blueprint
3. Attach the variable "New var 0" to the instigator pin
4. Compile

Result: The instigator pin will disconnect

Expected: Successful compile

Updated Repro Steps: 

1. Create a BP based off of Pawn
2. create a "Spawn Actor for Gameplay Task" node
3. Add an Actor Class variable that is a class reference
4. Connect actor class variable to the "Class" input 
5. Add "Get reference to self" node to the "Instigator pin"
6. Break the "Class" connection
7. Re-connect the Class connection

Result: Instigator connection is broken

Expected: The pin stays attached
