Crash occurs when the user select an AI-controlled pawn while simulating in viewport. This seems to only occur if the pawn is moving or getting directions from the controller (example, if you select the pawn before it moves, it won't crash. But if you have it selected while it starts moving, the crash will occur).
This does not occur in //UE4/Main or //UE4/Release-4.15.
RESULT
