Dispatcher event called from actor blueprint needs to compile in a specific order

Dispatcher events being called from actor blueprints have to be compiled in a specific order to successfully call the dispatch event. 

1. Create two blueprints deriving from Actor ( for reference in the steps: BP_A and BP_B)
2. In BP_A, add a dispatcher event and call it from BeginPlay then Save/compile
3. Open BP_B  and create a new variable of type BP_A. Save/compile
4. Place both actors into the level and reference BP_A inside of BP_B
5. Back in BP_B, create a custom event that prints a string and bind it to the dispatcher
6. Compile BP_B then BP_A 
7. Play 
8. End play
9. Compile BP_A then BP_B
10. Play

Results: Dispatcher is successful only when BP_B is compiled before BP_A

Expected: Dispatcher to be successfully called after compiling in any order
