Switching levels via blueprints crashes editor

Switching levels via blueprints crashes editor. This occurs using either "Execute Console Command" or the Open Level node.

Frequency: 2/2

CrashReporter: N/A

NEWEST REPRO

1. Open QAGame in editor.
2. Make sure you're signed into source control.
3. In the Content Browser, rename QAEntry to "NewTest".
4. Open QAEntry (this particular step seems to trigger the crash. Doesn't occur if you don't at least open the level)
5. Open a new default level.
6. Play in viewport.
7. Run the console command open QA-Promotion.
8. Once QA-Promotion opens up, run the console command open QAEntry.
