Using a Macro to access a variable from another Actor causes a crash in Standalone

Using a Macro to access a variable from another Actor causes a crash in Standalone. This does not seem to affect any other preview in editor, nor packaged games.

Reproduced in 4.7.6, 4.8 Preview 4, and Main (//depot/UE4/Promotable-CL-2578133)

1. Open a new Third Person template project
2. Open the ThirdPersonGameMode Blueprint
3. Add an integer array variable
4. Add an element with a default value of 1
5. Compile and save
6. Create a new Macro Library of type Actor
7. Add an output of type Integer Array
8. Get Game Mode > Cast To ThirdPersonGameMode (pure cast) > Get Integer Array > Output
9. Compile and save
10. Open the ThirdPersonCharacter Blueprint
11. Add an input key event
12. Get the Macro created in the previous steps
13. Get (Index 0) > Print String
14. Play in Standalone Mode
15. Press the input key

Result:
The Standalone Game crashes (the editor does not).
