Crash rebuilding Class Hierarchy

Hi,
I was following Enter/Exit vehicle tutorial, (Point 4)
https://docs.unrealengine.com/latest/INT/Gameplay/HowTo/PossessPawns/Blueprints/index.html#entering/exitingavehicle

When doing this point in editor it causes it to crash, I have tried on a new project and also in some of my other projects and it still causes it to crash.

Hi ,

Thanks for report! This crash was also reported here:

and a bug report was created for it (UE-17673). I’ll be updating that post as I see any progress on bug report. If you have further information to add, please do so on that post. Thanks!
