Event Dispatcher not being called in 4.6

ED nodes in 4.6 but are not being executed in standalone or cooked games. Also, users receive compile errors when the project is saved and reopened that resolve when the blueprint is recompiled.

**EDIT**
Only occurs in a standalone/cooked build.

**EDIT**
Bleeds187 mentions that changes to "//depot/UE4/Engine/Source/Editor/BlueprintGraph/Private/K2Node_MCDelegate.cpp [revision 33]" between 4.5 and 4.6 caused the problem and reverting back to the 4.5 version of the file fixed their issue.

1. Open UE4 Editor (any project)
2. Create a GameMode BP (EDGame)
3. In the graph tab, add a new Event Dispatcher (EDTest)
4. Add Event Begin Play node
5. Drag off of the begin play node and add "Call EDTest" node
6. Compile
7. Create a new Character BP (EDCharacter)
8. In the graph tab, add "Event Begin Play" and "Get Game Mode" nodes
9. Drag off of "Get Game Mode" and "Cast to EDGame" node
10. Connect Event Begin Play to Cast to EDGame
11. Drag off of As EDGame and add "Assign EDTest" node
12. Drag off of the exec pin of the EDTest event and add print string node
13. Compile
14. In World settings set GameMode Override to EDGame
15. In the dropdown for Selected GameMode change Default Pawn Class to EDCharacter
16. Save everything and launch Standalone Game
