CrashReporter User Descriptions:
1) New project (I used TopDown C++)
2) New Actor-based C++ class (MyActor)
3) Add MyActor instance to level
4) New BP class based on MyActor (MyActorBP)
5) Add MyActorBP instance to level
6) Save all
7) Change MyActor.h to add a new bool UPROPERTY (I called it 'bTestProperty')
8) Rebuild code in VS to trigger a hot reload (or just add a new C++ class in the editor which will also trigger it)
9) Open MyActorBP, click Compile, boom
